well i am new to the sport to and i never realy had any real thougth that went so deep as your but like you said it is your gun and a sin stock is more derable but lite so if recoild is a problem i think i would go with wood. you will find most guys out there are not to bad of guys and will do there best to help you learn the ropes my first time was a blast and the second came with them helping and suggesting. then they invited me on a pheasant hunt this sept 7 so they are so realy good guys out there and i do not own a sport type gun but food for thought sporting clays is kinda like hunting so why would a hunting gun not work ust as well the main thing i find is fit and the can be fixed on any gun.
