After a while I changed and decided to ride him with my english saddle... I've NEVER ridden him with my english saddle... I've only ridden in it a handful of times (literally) and have never done anything faster than a trot while riding in it.
I only ride him in the english saddle for about an hour, but we (I was riding with my cousins... they were all riding western) went through a trail and some other stuff... Within fifteen minutes of me getting on my boy with the english saddle, I was trotting and cantering him... (note, once again... I've NEVER cantered in the english saddle). However, it felt as though it was a little easier for me to stay in the english saddle when he was cantering. Yes, I got thrown forwards when he stopped suddenly, and I 'overrode' him a bit (I kept leaning forwards some), but he did perfect and it was so comfortable... for some reason, I felt more secure in the english saddle than I did in my western saddle, even though I lost my balance more than a few times.
I think I'm going to start riding him in the english saddle... it was just amazing at the difference and how much more secure I felt... and I have only ridden english a few times...
