I have a friend who is a few years younger than I am (ok, more than a few... I'm almost nineteen, my friend is thirteen... I think, she may be twelve...). Anyway, I have a ride planned with her (her name is Shanna) and our other friend (Brandi) for this coming Saturday. Brandi is fifteen, so I'm the oldest.
Anyway, Shanna is going to ride my mare Gypsie because one of her horses is too old and is basically crippled from lots of rough riding when she was younger, another of her horses is a nutcase and she's scared of riding him, and her other horse is getting over a bout of founder and doesn't have shoes.
Let me get on with this, though... I don't mind Shanna riding my mare. I actually invited her to ride Gypsie, but she wants to ride in my english saddle. Normally, I wouldn't mind too much, but seeing as how I have two western saddles and one endlish saddle, I'd prefer it for her to ride in my mares western saddle. I don't mind her riding in the english saddle, but my mare tends to buck and likes to kick up her heels when she's in a good mood.
Shanna is a pretty good rider, but my mare can throw some doozies and can twist around in the air like a fish outta water. I don't want her to get hurt by falling off the english saddle... i'd rather she ride in the western saddle that way she can hang on a little better if my mare does decide to throw a buck or two in. Plus, we're planning on riding up some mountain trails (maybe, I haven't quite okayed these trail plans just yet because i'm going to be riding my coming three year old and he's only been on two trail rides so far, even though he's been ridden a good bit since he turnd two and I feel very safe on him). But we're also planning on doing a good bit or trotting and a little bit of cantering... and I really don't want my friend to get hurt, though to this date she's never gotten injured on any of my horses, just her own...
What should I do?
ETA: also, my mare is used to riding in a hackamore and I've been riding her in a bit lately... and she's not really all that responsive to the bit anymore.
