ASW 27 vs ASW 27B

[Thor]

I'm looking at buying a ASW 27. The ASW 27 are usually 15k less than a ASW 27B, WHY?
Does the ASW 27B have an performance advantage over a ASW 27?

The B has wet wings which are a little more convenient to fill and may hold a few gallons more.Almost all have newer winglets, either by production, or retrofit.
Pricing has little to do with B or otherwise, and is mostly driven by condition and equipment. All other issues being equal, an early 27, with excellent finish condition, can easily be worth more than a B in poorer condition.
There is no difference in performance as they are geometrically the same.
Good luck

Are the 27B wings treated differently than the earlier models, so they
are less likely to develop "spar dips" from spar shrinkage?

No- in fact the thicker gluing used on the B's for water protection makes them somewhat more shrink prone from my experience.

Not performance, but other changes:
The B model offered an optional tail ballast tank, unavailable on the original.
The water ballast dump handle was relocated on the B to a more easily reached and less likely to be elbowed position.
There is more Carbon in the B model fuselage layup, making positioning antennas such as FLARM or TXP more critical.
As Hank mentioned, Schleicher wing tanks are more likely to cause waviness of the wing skins than ballast bags. Or perhaps most other manufacturers' wing tanks?
Also noted previously, the newer winglets work better. There are still a couple of 27s left with the old stubby winglets, but low speed handling is improved by the Tech Note 4 Darlington or Maughmer mod, or Nixon, Nelson, etc. winglets.
If you have to do the Tech Note 4 mod, make the tip skids taller at the same time to keep the ailerons out of the dirt, and include tiedown points in the tip skids.

Does the original ASW 27 have the ability to carry fuselage ballast of 35 liters like in the ASW 27B?

Yes, if equipped with optional fuselage tank.

If one is thinking of a asw27b is there another make glider one should consider before pulling the trigger?

Ventus 2 perhaps?

Yes, I would chime in ... just recently acquired a Ventus 2cT and can say it is a wonderful ship. Before that I owned an SZD 55 which I loved, too, but I have to say the difference is quite astonishing. All performance-aspects aside the Ventus is simply very nice to fly, especially to thermal. It easily centers in thermals and stays there even in higher bank angles with only minimal - if any - stick input. This is a very big bonus for me because thermalling could get quite tiresome at the end of long cross-country flights in my SZD which always needed attention while thermalling. I don't know about the prices in the US but here in Europe 27s and Ventus 2 (without engine) are at the same price level. Other bonuses: spacious cockpit, easy to use water ballast and you might even be able to shoot a C model with 18 m wingspan.
