I’m running the Duros and like them so far. Haven’t had them in water deep enough to float yet, but that’s a VERY small percentage of what I’ll use it for. Tried running forward and backward and couldn’t tell enough difference to put them back on forward. 2.5psi seems to be the sweet spot for me. 1PSI didn’t like skidding at all, 3.5 was a noticeably harsher ride so I’ve kept them at 2.5.
I was planning on trimming off a bunch of the nubs for better skid, but after finding good pressure haven’t felt the need enough to take the time to cut them.
