2XL, I find a low HH not very fun to get in either but Its not a problem for me. I am short so low and high are totally different from my point of view. Well shorter than 6'4". Also it depends on the tarp you fly. The Neo tarp I have lessens the coverage the lower I hand. I would assume that to happen with any diamond shape tarp. I am changing tarps soon to a MacCat or I will try and make my own as per Blackbishops instructions.
