It's interesting that there are no replies in this topic.. yet
I've been playing with classical Antis for quite some time now (also tried FL ones (ABS3 and 2)) so I'll try to answer this question.
So if someone says "spin reversal" - I understand it as passive spin reversal (without additional motions that add additional/active spin). So I'll base my answer on this assumption
So as a normal Anti I would define an Anti that can generate some spin and has some reaction to spin. But this ability (to react to/generate spin) needs some conditions - more sponge engagement and specific angle of the racket when one performs the shot. The topsheet is usually pretty slick by itself and has very low grip.
So with a normal Anti defined like this I would dare to say that passive reversal is minimal. A mean - you can easily kill the spin or you can actively support it and thus return some "active" reversal or (with some Antis this is easier than with others) you can create your own spin. But just passively returning the spin.. Yeah, it can probably return some spin, but it's not even close to the FL antis (I would say that if FL anti is a 5 in spin reversal, then normal Anti would be 0.5-1.5).
The easiest shot to have some passive spin reversal with my Anti for me is the heavy and slow topspin - and if I manage to take it of the bounce with forward motion - then - yes - some spin is left, but it's not a heavy downspin.. it's moderate at best.
