Figured I'd do a quick follow up.
Took my new Grapple out on a rec climb the other day and really enjoyed using it.
Right now, it's set up with a 20' 10mm lanyard (eye to eye with no snaps). I haven't taken off the tether at this point, so it's attached with a biner. On the other end I'm using a hitch climber pulley and prusik.
Made some small traverses in a large Sycamore tree with scaffolding branches. It allowed me to get in positions to set up good redirects and made for really nice work-positioning.
Can certainly see where this would come in-handy.
My kickbacks would be... it does add a good amount of weight to the saddle, but it's benefit could outweigh that.
It does feel a bit "clanky" when tossing it around in the tree for the first time, especially compared to the Captain Hook. Maybe because this device is two pieces that fold on itself, so there's a lot of noise when it's bouncing around in the tree. I found myself inspecting it for damage after most throws. Kept reminding myself that's what this tool is made for. Should be built to handle that type of use.
Overall, I'm pleased with the purchase.
I'm sure there will be a few things I tweak to my setup. I'll end up storing the Grapple and its rope in a small tool bag that attaches to my saddle. That'll help keep it stowed and tidy. I'll probably attach the lanyards splice directly to device, instead of the tether.
I'm pretty excited to use it more and figure out how to make it work best for me.
