Oh I just want to add, I usually ride (I DO ride) without it and I only put it on him on a lesson day because my trainer wants it on. We've been doing fine without it, I even cantered my first time off of the lunge (by myself basically) without the fork on and he was perfect.
This picture: http://a3.sphotos.ak.fbcdn.net/hphot...29386627_n.jpg is before I started lessons. It was very inconsistent roundness but he was beginning to get it on his own (mainly the sitting trot.) I think him in the fork is making him lean and he's backtracking. I've tried talking with my coach but she is persistent.
And if you have any advice for my canter, please please please let me know!
The time has come for the C word!
