A good boatman always blames the equipment in the case of a pin.
Recently did the MF Salmon with two passengers and gear off the top.
Launched on 530 cfs. I topped off a bit at the top of the ramp to rig the boat and didn't add air until Indian Creek. 16.5 foot Maravia with the kitchen box, tables, cooler, 4 boxes and other gear. We made it through many areas cleanly for the most part. A couple of the others got stuck and released air out of tubes to get unstuck.
But stay firm in your belief. Get it?
I am sure that your pin at Tipi Hole was uncomfortable to deal with but don't blame it on low pressure rafting.
Refering to risk of puncture. I am in a Maravia so for the most part I am unconcerned with puncture. Low pressure allows the tube to deform around the rocks more easily instead of getting stopped or hung up on them.
I will say that if you plan on hitting a lot of rocks dead center in the middle of your tubes under your oar lock a stiffer boat might bounce off easier. Or could pin you harder. As in if it is stiffer when it does sink it will push everything further down into the water.
