Thanks for all the advice so far!!!! I rode (and may continue riding, outside of lessons) a throughbred gelding that's a bit green...and not worked enough. He bucked me off the first minute I got on him because he was extremley "fresh" but after lunging him, with my coach's help, I did some trot/canter work on him and he was pretty good, after we worked out some small issue (mainly him testing me to see if he could get away with cutting corners, leaning, etc.). He has a very large sride, and I can't jump him yet, since he needs to be worked consistently and I need to be more comfortable o/f first. However, I think we may actually get on well together, meaning I can perfect my flat hunter equation when I ride him outside of lessons, and than do my over fences work/training on a reliable (slow... :P) mare during lessons. Hopefully I will be able to adjust, I just need to also get rid of some "pony riding" habits I have developed.
All I pay my psychiatrist is the cost of feed and hay, and he'll listen to me any day. --unknown author
