Hi Surfitz,
I rode the 9'2"Allwave and ProWave back to back and agree with your comments. The Allwave is as stable and as easy as it gets for me at 93 kilos even if it's a little choppy or washy (is that a word?).
The PWon the other hand required balance and concentration to remain upright and dry. In less than perfect waves, the AW is a winner, if the wave has a spot of grunt, and the conditions are cleaner, go with the PW.
A big difference between the two boards. Both great, just at different things.
