Slayer: I've shot through a couple dozen. They are heavy. But if you want more weight, why not get the 75-95 GTs, or the GT Big Game 100s (I'm shooting those, modified, now), and add the tip weight to get good bareshaft flight? The GTs are much thinner, to the extent that aides in penetration, and the increased tip weight will increase FOC and also aide in penetration, according to Ashby. I find the GTs to be increadibly tough, but lots of folks have had great results with Grizzlysticks. - Jay Campbell
