Dermot, this is super helpful. And you are I are practically the same size, so it's good to hear about how comfortable you were in the boat. And I agree a plastic boat makes sense for major rock hopping. I could buy the Karla AND the Delphin (or maybe a Stratos) for the price of the Sterling if I decided to go that route!i'm 6'1" and 200lbs with size11 boots.. the Karla was wonderful, playful, trustworthy - but we were in flat water (indian arm),
seems like it handles much like the SisuLV, but lighter / smaller / and more responsive to small inputs
the Delphin i have is the 155 v2, the larger one, in corelight, and the oposite side of brackets around the SisuLV, the Delphin feels heavy, needs to be pushed to respond, it was great when i weighed 275, i could toss Delphin around like a toy, now that i've lost weight the Karla is just better for anything that does not involve rocks and/or a tent in the back hatch
i've been told the Delphin 150 is diffrent boat, and today it's probbaly a better fit for me, or most likely anyone looking at a Karla
one other thought.... the Delphin is a complete PITA after a few hours, i wedge into it very snuggly, but the feet cannot move what.so.ever.
so i'm wedged into frog leg position with no wiggle room - in the Karla there's absolutly tons of leg/foot room i could paddle with knees up surfski style, super comforatble for me
i replaced both the footpegs and the seat in the Delphin, have not felt a need to do that in the Sisu, identical outfitting in the Karla
one thing the Delphin has going for it is the (near) unbreakable build. truly takes a licking and keeps on ticking
