I've shot targets with a compound and did my hunting and fun shooting with a recurve/longbow for the past 25 years. No problems. The way I approach it, I've got a totally different mindset with the compound than I do with the stickbow, totally different shooting procedure. If anything, shooting the compound improved my stickbow shooting form. At the same time, shooting the stickbows strengthened my muscles in the final draw length range of motion, which made my back tension shooting more powerful and fluid. Each style feeds the other.
