In general, 7-Cells will come in steeper, be more stable in deep brakes
(tough to collapse), less likely to have collapsed end cells, and are
considered more docile (although that's not necessarily true).

In general, 9-Cells will have a flatter glide, are easier to collapse and
will fold like a bow tie when you do, and are considered to be higher
performance (although that's not necessarily true).

The difference is because in general 9-Cells will have a wider aspect ratio.
There's less pressure to keep the outside cells inflated, but those cells
contribute more to your turns. I've been told the wider aspect ratio also
generates more lift for the same sized canopy, but I can't quite sink it
into my head why that would be so...

There are plenty of very tame 9-Cells, and you can load a 7-Cell Triathlon
or Spectre up and make it plenty snappy. 7-Cells are preferred for crew.

There are odd ball exceptions too. I believe the Extreme FX is technically
a 7-Cell, but it has this cross rib thing going on and is one of the most
radical canopies out there.

My advice would be to hold out as long as you can without spending a lot of
money. Either buy a used rig now with the intention of getting the gear you
really want after you decide what matters to you or rent until your sure
what you want. For instance, I really enjoy flying my canopy - so much so
that I tend to pull as high as I can without causing trouble so I can do
more spins and carving turns before lining up for a fast landing. Other
people like to just float around and enjoy the view and don't really want to
sprint when their feet hit the ground.

You're on a steep portion of the learning curve. In the next 100 jumps,
you'll wonder what it was you were thinking in the first 25.

After you figure it out, demo a bunch of canopies. I went in dead set on a
Triathlon (a 7-Cell). I had heard nothing but good reviews, and liked
everything I read about it. When I started demoing, I realized that the
size of chute I wanted meant I was getting away from the things I liked
about the Triathlon anyway. I tried a Sabre (a 9-Cell) and loved it. If I
had just ordered instead of demoing, I'd have paid a pretty penny for a
canopy that I really didn't enjoy.

It starts out with 2 sets of questions. 2 questions in each set.

FIRST SET------
Do I want to buy new or used?
Do I want to buy it piece by piece or all at once?
SECOND SET------
How much can I spend?
What's the best deal?
Many more sets will come into play once you answer the first two. I'll save
the 7 vs. 9 cell canopy debate for someone else. Just remember to have fun.

Too much fun

Surely you have an opinion on this since you demoed both 1 and 9 cell canopies
and bought the 9 cell. Don't you wish you would have bought a smaller 9 cell?

To a fault.

I haven't demoed the 1 cell canopy yet. Maybe at Quincy next year. I do
prefer my Sabre though.

He demoed a _ONE_ cell canopy?!
COOL!
Where can I demo one?

Would a ParaDactyl qualify? It's as scary as you'd expect a one-cell to be.

I would think a 'Dactyl would be a two-cell canopy, unless you got the
double-keel, and then it would be three.

And now for a little topic drift... For my money, the Delta2 (delta-death)
would be the one cell canopy to avoid at all times. Of course the last time
I saw one jumped was while I was a student in Cushing OK - just over 19 years
ago. John A-6504

'Dactyls were OK, didn't Vision/Coors jump them for a couple of months?
Now if you wanna talk scary, how about that Delta "Death" wing?

That's the one I was thinking about. Carlos kept it under his packing
table and offered to let anyone jump it, but I never saw anyone take it
on. Who finally jumped it? Fergy?

Jeesh! What is the average age of the readers in this ng?
Next you guys will be discussing the merits of OSI's vs ropes & rings,
and whether the CrossBow is superior to the Papillon.
(Not that I know what those are.)

I jumped mine three months ago..... into the water. And being a single
keel parawing, it would probalably qualify as a 2 cell canopy.

And the preferred name we had for them was the Dildo II Paranoid.

Ah, yes, one more thing I now wish I had written in my log book. One of the
problems with memories after you start celebrating Jack Benny (Who?)
anniversaries for birthdays is that you no longer have total recall. I think
it was Carlos who jumped it - - perhaps some of the others who were there in
the summer of '79 could provide details since I was busy working on falling
stable and intentional turns - Mike Mangold, Geno Johnson, Fred Leslie, John
Robinson, John Harmon - - jumpmasters extraordinare. John D-7408

OSI - Opening Shock Inhibiter, found on Paradactyl-class canopies
(single-surface gliding canopies). Ropes & rings - what we had on
squares before we had sliders. You're comparing apples and oranges. :)

Yes, but they were both devices to lower opening shock;
It just happens that they were never used on the same types
of canopies, (at least in PRODUCTION canopies).

OK, show of hands; How many people have jumped a volplane?
Bonus question: Why would a volplane owner occasionally
have the problem of hydraulic fluid all over his canopy?

Never jumped one myself, but knew a few folks who forgot whether they
set the reefing system for hop-n-pops or terminal openings.

Me. (that's as close as I can get to showing my hand)

The Volplane had a hyrdaulic reefing system.

What do I win? A new Sailwing?

Intentional water jump. I did the hat-trick that weekend. A Delta II, a
Mark II P.C. and an MT1X, all into the water.

But I candy-assed out. Did a Hop & Pop without the OSI.
