Don't limit your choices simply because of the rotating head. If you are shooting a D-loop whether the head rotates or not makes no difference. The 1/4 twist you put in a D-loop with a non rotating head has no....zip....zero....nada effect on accuracy or shootability.

IMHO, I would shy away from the rotating head. If it is not in the same position shot after shot then it will be a detriment to accuracy (That comes from personal experience)
