Formula 100 plays like a clone of the APDGT, almost exactly alike except for slight weight differences and the F100 has much better comfort & feel, IMO. As an APDGT owner and user for the last 2.5yrs, between the two I'd easily pick the F100.
Pro 1 16x19 is a player's racket with a lot of pop. It feels and plays much heavier than its specs suggest, IMO. If I didn't know the specs I'd think it was a 12oz players racket.
