Thanks @SkiJay ! I've been bolting my Sequence plate down to my Mapple 6.0 using washers and the rear horseshoe. I don't use the special "floating" washers, so I always wondered if I was compromising the performance design. I met @eddie_robberts_jr at a Broho tournament and asked him to take a look at my setup and he said it should work just fine, but I still have the two single plates that the Stradas came with, so I may switch them out.
Unfortunately the only skiing remaining in my season is a week on Kauaii at the end of the month, and I'm planning on switching to my GatorMod Fogmans next season. I'll certainly remember this if the Fogmans don't work out.
As a sidebar - someone on this forum flex tested skis with dual locked binders vs plate binders and found the dual lock to be stiffer. I don't know the parameters of the flex test, but he's a well respected Mega Baller.
