I have had the Lynx on the Sacramento Sims to Vollmers run, the Trinity Pigeon Point section, and the Rogue River Graves to Agness wild and scenic run. The main difference I noticed with the Lynx is that it seemed a little more stable on the drops probably due to a little more rocker than the Strike. The Lynx makes you feel a little more up in the air than the Strike so logically it seems the Strike would be less tippy, but I feel the Lynx is very stable.
The Lynx is about $350 more than the Strike and you get 4 less lbs, 1/2" larger tubes, and a 10 year warranty vs 5 for the Strike. It is a tough call whether the Lynx is really worth the extra money. I can say I really like both boats have no regrets on purchasing either one. The deciding factor would probably be that if you are doing rapids with lots of 3' or larger drops you might find the Lynx worth the extra money. If you are doing Class 3- and less, the Strike is all the boat you will need.
Pros: light-weight, cost, maneuverability, surfing, fun-factor, lake paddling. The tracking fin is great for lake use.
Cons: my model was only rated to 180lbs - a 250 lb friend used the boat and had great difficulty with tipping over. I would be reluctant to try this boat in Class 3+ water, but, maybe I should try it - it always amazes me. Small boat for overnighters. Though the boat is tough and handles srcaping over river rocks, it is susceptible to pin holes from things like blackberry bushes.
