I've paddled both and I like the 11'4" better.. It surfs waaaaay better than the big 11'6".
The Naish also has that great new handle.. and the AST is a very good price.
Andy Davies did so well at the Corona in Merimbula last Nov and you should have seen him on his 11'4"... Amazing.
Nothing wrong with the 11'2" Blend either.
This is Andy and his GF and they're both on 11'4"s.. She's on the new AST.
