yo jim if your are 6'3"your poles are not to long, i can tell in your picture you are bent to far foward, you need longer poles, try lighter ones.:blink:
Not sure which pic you're referring to, but bending at the waist is always my biggest technique issue. It seems to get worse when someone is taking pics.
Anyway, the bend isn't because of my shorter poles...I had the same issue with the longer poles, even as long as 52".
