Some easy Class 4+ with some 10-12 foot waterfalls.... and in the pool dialing in the fit and getting a feel for the boat stability.
It's a sweet boat, the last 3 boats I have owned are the Dragorossi Critical Mass, Habitat 80 and JK Mega Rocker. The Stomper 90 is a better overall boat than all three.
Ridiculously easy to roll like the Habitat but MUCH more primary stability. Has the same hull feel as the CM but overall much friendlier and easier to move around. I really didn't like the Mega so the Stomper kicks the crap out of this boat.
All-in-all, the Stomper 90 is a sweet creeker with what I would consider the perfect combo of volume distribution, primary and secondary stability, comfy outfitting and a hull that is probably the best hull design for me and the places I paddle.
The only negative right now..... the bump behind the cockpit beats the crap out of my shoulder on backdeck rolls
This happens is most modern creekers with me though and after a 3 year hiatus from paddling I can hit my back deck rolls and almost 100% of my hand rolls in the Stomper, something that I couldn't do even when paddling fairly regularly in the CM or Megarocker.
