Of course subjective but currently on ART999 with a cut down 420 tail. Competent (+) rider. Mostly prone surf but sup and wingding in waves. 350 or 375 progressive? ART 899 on way....
I enjoyed the 380 speed tail with a -1. Very loose and fast, easy to cut winglets off to loosen it up further. I wouldn't get a 380 though. get a new progressive
Been using 350p with 899 and 1099 .. noticeable improvement from 400p on both 99's at my weight (68kg).. winging, prone and dock.. looser, faster and less tendency to stall .. highly recommend 350p
agreed on 325P. If I could get a 300P I think that would be great. The X99 series just seems to come alive with smaller tails. They feel like a dog (in comparison) with the wrong tail.
See that your asking for "all around", I would chose the 400P if you are above 180pds. Below that the 350P would serve you well. Anything smaller will tune towards performance and away from Stability.
