Yeah, i know how bad it is to having a rearing horse. I've ridden one before haha. But Spider doesn't have a habit of rearing, he only does when i first hop on. And i've been riding for 8 years haha. And Spider was broken in by Bill Church. I don't think u would know him, because it says on ur profile u live in canberra and i live on the Central coast :) And he was broken in in 2008, and i had broken him in and we had gotten as far as trotting (with a rider) but then we found out he was 2, so we let him out to grow and recently in November 2009 he got re-trained by Bill. Spider is a treat to ride, but he can be a little bugger some times. And Bill said "Spider is just full of bluff sometimes" so yeah, so the rearing thing isn't a BIG problem, he doesn't try to throw me off. I just thought buckers and rearers needed a martingale? I read somewhere that they should. Hm well, if i don't need to use one i'll forget about it :)
Thanks for ur help!
