I can sit flush in a trot! I havent tried a canter yet! I do have an awesome OLD OLD mare that stops if she feel the rider become off balanced (she is about 27yrs old and we rescued her as skin and bones! But she's packing weight on1!!) It's awesome to have her around though, bc I don't dare try it on my 5yr old arab cross mare. She may be ok with it, but I don't want to chance it! And I have stayed on in one of those arab spooked where they do a 180 spin sideways! I was bareback and for some reason that day she thought the AC unit was going to eat her! My arms bounce alot when I'm in the saddle in a trot though.... I can't seem to get the hang of the flow when in my saddle. It's almost natural when I'm bareback....
