Heck yeah, get a pair of small (not extra small) rigging plates and you’ll have an amazing work saddle with lower Ds like on the TreeMotion and Ergovation.
The TriRig plates from Rock Exotica are really nice and pretty affordable. Little less cash than Petzl and DMM, then you can just replace the bridge easy peasy with bulk rope and stopper knots.
The original TreeMotion and TM SuperLight bridge is Globe 3000 from Teufelberger, the Ergovation is Fly, the Onyx I think is Platinum, the Monkey Beaver is Samson 16 strand BRW.
I got some new scraps of Fly, 16 strand XTC Fire, Drenaline, and Poison Ivy. You’re welcome to enough for a bridge length of each if you want. There’s probably others in the tote I use for odd bits and bobs.
