I would also recommend a mechanical...larger cutting diameter the better. Even with the wide blades, these are tough birds to bring down, so shot placement is critical. Last spring I shot a big tom broadside with what looked like a good hit(knock him down, but must have been a bit forward) and he flew off with my arrow...we looked for him for two days with no luck. I was using a 100 gr. Spitfire w/a adder behind it, usually a good combination for me. If I hadn't seen it with my own eyes...I wouldn't have believed it.
