Would like you opinions on the two, I am currently following the advise of the 'back lady' and lunging my horse in side reins (with her saddle on). I've thought of getting a roller but would I be spending an unneccessary amount of money on one when a saddle does the job just as well? By the way at the moment I have no intention of using any other training devices on her, just the side reins for now. Are there any advantages that the roller has over a saddle other than the fact you can use more things on them?
