gold tip xt hands down tuffer and the straitness is .003 which is way better than most they aslo make the pros at .001 and the expdition hunters that are .006 i think the epics are .006-.005 if i remeber right the xts will prob be a bit more but worth it. i shoot them out of about 7 bows and all bows like the xts a lot and my wife and brother shoot the expeditions and do very well with them
