Yeah I'm shootin 315 fps and 78 lbs KE with a 352gr arrow at 70lbs with 30" DL. Is what I was thinkin about doin was shootin a heavier arrow with the speed mods to have relatively the same speed but gain KE at longer distance impacts because we all know heavier arrows carry move KE and drive with them farther. I'm one of those guys that likes to shoot long distancesyet wants plenty of drive on my arrow (exspecially for elk) but my light arrows shoot so flat I love it but am worried about drivinthose light arrowsthrough an elk at 60+ yards and maybe try a cowat 80 yards (only if the situation is right). So I guess I'm just thinkin about what to do. I know this setup is plenty good forshootin a deer out to 60 yards but just thinkin about what would be best forout west shootin heavy boned elk at longer ranges.WCL
