yep, same experience by me...
I fit in the small leg loops (with plenty of room to spare) and medium waist belt. There was no way to wear the harness without exchanging the swami belt and leg loops from two different sizes. The small waist belt was too tiny and the medium leg loops were huge.
Worst part was the the vice they created between your legs and the crushing of 'man parts'.
The leg loops are too wide on top and the sides were they come up from under your legs. This has two negatives...
When you high-step the harness cuts into the top of your leg/hip area and impedes movement. When you belay or take a fall prepare to have your junk crushed by wide leg loops scissoring your nuts.
