The can definitely effect a horse's gaits. It may not be effecting how it feels to you, but how your horse actually moves. A saddle that doesn't fit quite right or is not placed properly will inhibit the horse's natural movement, making them tense and either rough/choppy or very slow & short strided.
Is the roping saddle yours? If so, you'll need to sell it. If not, and you'll be buying a saddle for your new horse, you need to find out extactly what model and bar type (Semi-qh, full qh, reg qh) the Circle Y was that you rode her in, and buy one of those. Try to match about the same year make as well. If it was an older Circle Y (pre-1992), then the newer models may not fit the same.
The seat size is what fits you. The bar type and gullet width are what fit your horse. Also total saddle length is important. If it's too long it can be uncomfortable for the horse. You want the front conchos to be 2" behind the back edge of the shoulder blade. When placed correctly, the back skirts should go no further than the mid-line of the horse's flanks.
