If you are going to bother, why not fit two? Put the two rim locks
almost opposite each other, 90deg off the valve stem. Putting one rim
lock a spoke off of exactly opposite will offset the weight of the valve
stem. I did this, and only needed a .5oz weight to balance the front
wheel. And with twin rimlocks, you can ride a flat without the bead
breaking loose.

Totally depends on your tire. GP110 has a pliable carcass compared to a
D606, but with rimlocks you could go to 12 or 10psi and improve your
soft-terrain traction.

I've cracked and dented a stock KLR front rim without getting a pinch
