Pole shopping is fun! The ultra lightweight poles are really nice and won't wear out your upper body, but cost a lot more. Clip-lock poles are more reliable, especially in winter, but are also more expensive than the twist-lock kind.
My personal preference is for three-section poles, because they fold up nice and short and can ride on the pack for the uphill, then come out for the downhill. Two-section poles don't go as short, and will bang into overhead branches.
I don't think anyone makes a three-section, lightweight, clip-lock pole, unfortunately.
Good luck!
