Layups for the XR2001 vary from 350lb for carbon fiber to sub 450lb - 600lb+ for glass. The current drag hulls are probably too light for every day use as a lake boat but I think the 600lb river racers are overkill. The way they build the new ones, 525-550lbs would be a solid boat for daily use and run high 90's - low 100's with a 200hp motor.
An XR2001 is probably the most forgiving, easiest to drive and safest boat Allison makes. Also a LOT of fun to drive. The biggest let down you're gonna have going from a GS to an XR will be the storage. The GS spoils you in that department. Working around inside is a challenge but imo its not that big of a deal.
