I tried an SBS, then a suber panel Ffa and bought a prolite Ffa but at the end of the day, it didnt fit my horse (it bridged) and it didnt fit me. I had to have my girth done up as tight as I could get it to keep it from slipping and I gave up.
Ive not got a WOW for not a lot more more money - and I couldnt recommend it enough.
lol-I didnt feel like that although I did initially feel away from horse's back a bit. It took a little while to adjust to it- it was a week or so until I was convinced although neddy was convinced much more quickly! sitting on anything else now feels horrible
