I am big Monica, and I ride in a Sensation hybrid. I sorta "spill over" if you know what I mean, but its like pants, I can wear size stretchy 14 but I realllllyyyyy wear closer to 18. I could get a bigger saddle and just spread out into it more. The sensation hybrid is best for my horse tho. I have four horses I ride regularly and two of them have to have saddles just for them and two of them seem to act and move like they wouldnt care if I duct taped a folding chair on them and rode in it. But the sensation works for them too so why not. I had a hilason and a trekker treeless and the deal with those was that the stirrups are hanging in a fixed position that because of my body shape made me have to sit perched forward. I always felt uncomfortable! and its not good for gait in most horses I would say. wasnt good for mine! also it outs you in "launch position".
with the sensation you can move the stirrup hangers around until you get your natural position. I also could use the sensation stirrup hangers on my Trekker which was a godsend. but I sold it to buy a sensation. but the sensation stirrup hanger thing was only about 20 bucks. janice -- yipie tie yie yo
