I get it from owning a 06 charged gtx barge for 2 years and riding nearly every weekend with 3 other friends with charged seapoo's one of which is a brand spankers wake edition which still feels heavy.
Theyre fine if you want to go fast in a straight line but if you want to throw them about in the air they dont respond as well as the smaller lighter ski's. Not to mention having to push the dam things up the ramp because the recovery quad has died.

xp's are one of the most responsive 2 seaters of that era which is why they won so many race's. they have exellent power to weight which makes them brilliant fun in the surf and even better with a little more brap

opinions on ski's and branding are very much as diverse as in the car world, personally i cant afford to buy an new ski but even if i could i wouldnt as my mates new (only 12 hours so far) 4-tech is not as responsive in the chop as my 10 year old 2 smoke xp (even if i do get thrown off much more often)
