I ride a lot of WKND boards, but the FA I am rocking at the moment from BBS has a slightly steeper tail. Very similar measurements, all 8.25s. Similar decks all round, although for me the FA appears to have better feel in the pocket (who knows if this is in my head).
Just my two cents anyway, and personally I'd rather support Grant these days and overcome these minute differences by just learning how my board responds a little better.
