You'll never go wrong with Thunderheads. They are tough and accurate. I shot one through a 45 gal drum three times before the blades exploded off the head and the head was pretty much perfect when all was said and done. There are lots of good mechanicals I like my Wasp mechanicals. Like Dan many people are turning to Slick Tricks. I've shot a few and the Wasps are the best flying broadheads for me to date. Haven't tried the Slick Tricks yet but I am sure I will be pleased when I do. I think you should shoot the most accuate broadhead regardless of any other feature. Yes I do double band my wasps although I know they will not open in flight. Either way they give me the most confidence which will give me the most success.
