Thanks! Well, no, I do not have a flank cinch. Reiners around here don't use them, so I have just never gotten one.
I will try tightening the saddle more before the walk, but I also don't want to make him cinchy-he tends a bit that way as it is. I thought I had it rigt, then when I got this new saddle, I took pics of it to the dealer, who told me that I was putting the saddle too far back, to put it up farther and let it slide into position...so that is what I have been doing. Another trainer had told me that also. I would take the dealer with a grain of salt, normally, but they are well respected custom saddle makers and huge in the AQHA, so I figure they know their stuff. It is definitely worse with this new saddle tho, which actually seems to fit the horse better...
Frankly, the whole english thing was so easy...pads were attached to my saddle, stayed put, and none of this mess.
I did get the 1/2" 5-star purposely, since I was always using a pad over it for looks. Total, that made 3/4" of padding.
