That's too funny Brusier, my JP 8'8" surf wide body also ruined me regarding my 9'6" Prowave for pretty much the same reasons! So I'm in the same situation as you are, looking for a more capable "bigger day" board while still trying to be realistic about the waves and conditions I surf most often.
I believe it says more about how nice a design the surf wide body is in every respect...for a bigger surfer (especially) in marginal conditions than taking anything away from the Prowave, a completely different style board.
Spent time on the JP Surf 9'6" and loved it...fast and controlled with just the right progressive rocker line and thin rails. I could really lean a hard bottom turn and rail to rail transitions were smooth and quick while also being very stable and fast paddler.....but felt I could have gone smaller still with the 9'2" surf and gain in performance. I'm 6'4" and under 200 lbs these days.
I'd pick the 9'2" to go along with your 8'8".
May look into the new 9'2" Prowaves as well when they show up as apparently it was redesigned from last year's model in a good way but would definitely have to see and try one out first to be certain.
I have an order in for an 8'9" Jimmy Lewis World Wide (which is a shape that I'm really excited about)with my local shop, but who knows when and If it will ever actually arrive so not holding my breath
And there's also the JL Stun Guns, which guys seem to really love.
I'll have a pointy nose pulled-in tail board by the end of August. Keep us posted with your search.
