What is the best pads to use for a flex tree saddle.  I have a horse with high withers and when I had him chiro, this seems to be the only place that was out, not to bad but I wanted to see if a pad might help prevent it from happening. 

I'm thinking a saddleright pad since they move with the horse and saddle. Might be the best way to move with the flex tree. I know Felicia at Horse tack world recommends them to be used with her flex tree sadles. 

We both have Flex2 trees & use our 5 Stars.  If your horse's withers are high, you might consider the Flex Fit style 5 Star
