I'm picking up a Triumph Tiger XC this weekend and I think the Pak-Meister Panniers would look great on the new bike! Question is, which size, 29, 41, or one of each? And which rack and mounting system would you recommend for durability and ease of pannier removal? I'm new to hard cases and mounting racks, so have no frame of reference, and would really appreciate some guidance regarding the hardware and frame. Thanx!
