1- Definately shorten your stirrups.The correct position for english riding is to push your weight down into your heels.That will help to keep your legs in the right position. Everyone,very much like horses has a stronger and a weaker side,so its very common to ride better on one particular rein,meaning clock wise or anti clockwise.Unfortunately you`ll always find that your weak side is also the horses weak side usually due to the rider not riding the horse evenly balanced,and lets be honnest we are all i think gulity of that. 2-No,never been. 3-Do you trust your instructor? surely they wouldn`t have recommended this horse if they didnt think you were capable of riding him.I really do understand your predicament,and I understand the worry of you ruining him but I would be more worried that someone who didnt have a clue what they were doing but thought they were an expert would ruin him.You are obviously very compassionate and its lovely to hear someone being totally honnest regarding their ability but I think that you could maybe learn alot from this advanced horse.We are all on a learning curve.Trust me,I`ve been riding 21 years and Im still learning.I`d say go for it! you wont know til you try him and if need be you`ve always got your instructor to help should you run into any teething problems
