I'm new to HF and also to whoopie suspension and was wondering whether there's an ideal diameter for toggles used in the marlin spike hitch?

What got me to thinking was that I cut, peeled and sanded a couple of trail sticks from a hawthorn, about 4" long but only approx 3/8" thick. They are extremely light and strong but does the diameter affect the hitch???

Regards, Matt.
