I started my daughter with the PSE spyder and she loves it. The Spyder S4 23”/40# is fully adjustable from 21”/25# to 25”/45# or there is another configuration with the same draw lengths but lighter draw weight. I started her on 10# to 30# configuration, but that draw length range probably will not work for you. Good luck and have fun.
