But I would think the wrap around ones would offer mounting points too fifth high and too close to the rider.
I mentioned HB because they are more toward the front of the bike, giving a little more room to stretch out.
Assuming you can mount the pegs so they are far enough outward.
Actually, my frame sliders are mounted in almost the perfect place, to the mounting point where the upper and lower frame down tubes bolt together. If they were wider they'd probably make decent highway pegs.
