I thought about it this morning, and I had picked out the PA68 with its 52.5cm width. Both my 2004 Evo 74 and 2006 PA80 are 56 wide, which explains why they are close, but the Evo is bumpier in a straight line, and the PA much faster, but the Evo better on lesser waves.
The 2007 PA 74 sounds good to me now, I have had an earlier Acid 74 and loved it, and this board may suit my local spot better. The Evo 74 I think I'll sell, and run the 2007 PA 74 alongside a 2006 PA 80, and I then have a 2006 Evo 91 for the lighter stuff.
Thanks for all the help.
