The principle difference is the B has a wet wing making it easier to get
up
to gross weight.All winglet variants are usable on both types.
Very few 27's are still being flown with the original small winglet. Mine
came off after the first flight.
No handling difference and any performance difference is due to condition
and preparation. They are geometrically identical.

I have a 27a with the small winglets and regularly fly alongside 2 other
small winglet a's and several b's with the taller winglets. The geeks tell
me that the taller winglets offer better low speed thermal handling and
that the smaller winglets have a teensy bit less drag at higher speeds. To
me the only apparent difference is (as is often the case) the nut behind
the stick.
