I hadn't considered the grip size being a possible cause. or at least making me grip tighter.
This is a GREAT description of what I meant when I posted, "Focusing on pushing my elbows are far down as possible."
Since we're here I'll add that, I don't get any "aches or pains" anywhere else and I did a 1500 mile Iron Butt on the stock seat. The bikes too perfect for that.
