The PSH wide ripper and the extra wide ripper are 2 different boards in regards to width obviously.
The EWR might suit you better than the WR for stability.If you can go the narrower of the 2 it would be better IMO.
Either way ,they are both great boards in the surf and you won't be dissapointed with either.
I ride the 9'2 Hull Ripper and the 8'6 WR and they are both awesome boards. The 9'3 sub vector with future controller rears and PSH quad rears goes off as well.
Ride the PSH with the PSH quad fin set up and you will love it

Give AA at Balmoral Boards a call as he know them inside out.
