Gidget seems really comfortable in that saddle. She moved with great freedom and stride and was really engaged in her surroundings wiht a bright attitude. It was cute how you gave her her head to go up the hill and she went for the grass. You know, give 'em and inch and they'll take a mile!
I like what I see betweent the two of you. I think, with G being still somewhat new to you, that you are just beginning to enter the place where you start to really know you horse, and I mean just barely begininig. It takes at least a year to have any real feel for a horse, and two to feel like you know each other well. I think you two are extrememly well matched. She is a sturdy little horse with a lot of character and you have the beginnings of a good seat.
You can feel how much harder it is to keep your balance in a treeless. It's really important to NOT stiffen up. you have to stay really soft and united with her movement. A saddle can mask it when by stiffening a rider's body movement becomes seperate from the hrose's , but a treeles, like bareback, can't hide it.
So, stay really loose and let your legs drape down. Don't put very much pressure into the stirrups at all, but rather really ride from your seatbones and draping thigh, like an Indian, if you want a mental image.
I, personally, would not take my horse out on the trail in a bitless until I felt that I had a whoa and a turn when I wanted one. If the bit is well fitted, they can easily graze in it and can carry it for hourse without discomfort.
Still, G carried her head without defensiveness, so maybe she would be happier in a bitless. Just make sure you have confient brakes before you get out there. You could always pack a lightweight bridle iwth bit in your saddle bag.
I would have like to see that canter. Oh, and do mind your girth. Remember that thread I posted on having my girth slide? I went off , but forturnately on ly at a walk. Amazing how many people had similar stories.
