dougb,
My Jab, from day two, has had the gloss knocked off, which would explain some of what I'm seeing. I left my Exile at box finish, which, consequently, needed some real friction to grab, but then it was very angular for me.
Even when I tried the Jab with polish side-by-side with the Exile it was easier to predict where it was going to finish. We all bowl on varying conditions, and our physical games are different so it never surprises me when another bowler, such as Channelsurfer, sees something different than I do. My Exile now belongs to another bowler who loves it, but for me my Jab has been hard to put down.
