I play on a Martin Magna (.484 bore, 6" bell), as well as doubling a lot
on the trombone, and it's my experience that a large bore horn will play
a lot freer - loads more flexibility, to the limit of your chops, but
will also require a lot more air, will have a darker, richer sound, and
will limit your range somewhat until you get used to it. A lot of
players depend on the feedback they get from smaller bore horns to
reinforce their chops in the high range, and when there is no blowback
(or very little), you have to do it all yourself. When I put a 1C in the
Martin, my range drops dramatically, but the sound is so full you can
slice it and serve it on bread.
On the other hand, I find it difficult to play on a small horn at all
now, unless I use a really big mouthpiece.

Jonathan,
I have been playing a ML Back with a lightweight 72 bell for
over 20 years. I have also owned a Large bore with a 25 bell. For me
the practicality of the large bore was not worth it. I definitely like
the sound and responsiveness of the Large bore but in playing long jobs,
the large bore makes it difficult to finish the race.
I have had several posts lately discussing the Yamaha "Z" step
bore horn that uses a Large leadpipe, medium valve bore (.435) and large
bell (.470") to a five inch flare. The smaller valve bore has made
flexibility and endurance much better and the upper register is more
"slotted". The large bell gives the easy reponse and warm sound. It's
kind of a hybred, but it works.
With the Bach's, the 72 is the largest, darkest bell and comes
with a 25-O leadpipe, which is more open than the standard 25.
According to my most recent Bach catalogue, the 72 bell only comes on
the Medium-large and the MLV (.453 valves and .459 bore). The MLV uses
a 43 leadpipe as standard.
Forgetting all the numbers, what is important is the sound YOU
want to have, but be sure you get to play the horn in the settings that
you use it before you buy it. If it's not too taxing and you like the
sound, go with the Large bore.
In general, Large bore horns usually have a darker sound, are more
flexible, and more difficult to play softly with support. ML bore horns
usually produce enough volume, put a "bite" on the upper register so
that it cuts through, and can be played quitely more easily. Endurance
usually tends to wane on a large bore.
Moral of the story: Different strokes for different folks
