Magnus are a good head, thunderheads, muzzy, steelforce, as for mech, there is only one I'd shoot NAP's 100gr spitfire pro series, proven in my tests to be well above the rest in durability and strength. Those spitfires are made just plain tough. Sure their blades may bend but the won't explode like others, at least you have a chance if you make a less than perfect shot. Good luck.
