Since I have been foiling, I sail a lot more (more sessions and longer sessions) and I also unhook much more and sometimes ride swell one handed unhooked riding with a partially powered sail which is fatiguing. Anyways, my forearms are a bit sore, certainly more than normal and as I am on the market for a new boom, I am considering reduced diameter and wondering if it would be less fatiguing

Currently using chinook pro alloy, and not at all likely to purchase a carbon boom, so I am weighing up the pro alloy RDM versus regular.

For those who have tried different booms what factors minimize forearm fatigue the most? Diameter, weight, alloy versus carbon, other...
