The comments about the Burn vis-a-vis the Jefe were not about the type of boat, but about the way they are expected to sell. Completely agreed that the Burn ought to have a rotomolded seat - any margin of safety has the potential to be helpful. However, as has been said, folks run class V in the H3 all the time and the H2Zone before that. The Diesel originally shipped with an injection-molded seat, an WS still had pics of folks in the gnar in the ads.
It's an individual choice. I don't run V+ so it's not as much of an issue to me. Yes, my objective risk would be greater, but I also know my paddling style, what I can do and what I am better off walking. I would feel no less comfortable in a boat with an IM seat than a RM seat for most of the runs I do. There might be some that I'd prefer a RM seat on for the increased safety margin, but frankly I don't paddle that close to the edge of my skills. And yeah, shit can happen (Pablo Perez, R.I.P.), but the logic remains the same.
Back in the 90s Riot did extensive testing on how boats hold up in pin situations. What they learned (according to Corran) was that every type of boat folded and that the real problem in getting out was the fact that the center pillar trapped the legs once the boat was partially crushed. Because of that, Corran designed his creekers without a bow pillar. So, while that does not prove anthing one way or the other, it would seem to indicate that under the pressure of moving water able to wrap a boat, not much makes a difference, so the priority should be ease of exit. Again, it all comes down to personal risk level.
Join up, suckas.
