I don't think there is such a thing as a finicky pick up on a chod tbh. They either nail it or they don't imo. Carp feed by sucking/blowing with various degrees of intensity. If intensity is low we don't stand a chance with a chod, zero movement, no potential for hooking.
Whack the chod on a boom and bingo, you have the HSR, which is a great rig in a low intensity feeding situation.
I only ever fish chods over weed or really, really heavy chod and even then I'll fish it on a tiny 2-3 inch boom. This makes it 10 times more effective imo.
