half saddle pads

hi! my horses saddle is a good fit everywhere except the front. he has high withers and so the saddle is a little low. as far as im aware it is a problem when jumping but not really flatwork. saddlepad also falls down even though i tent it. i dont have enough money to buy a saddle so half pad it...

They are pricey and seem a bit hard to find in the UK. Has anyone tried one? What do you think? https://www.thinlineglobal.com/shop/english-saddle-pads/cotton-trifecta-correction-half-pad Or This...
