I've had my Synergy for about a year now and have it set up with a Muzzy ZE, G5 peep, string loop, and meanv sts. I'm getting 294 fps with a 383 grain GT XT hunter at 29", 72 lbs. I've felt this is a little slow and wondered what I can do to tweek it to get more speed without shooting a lighter arrow. I've got a set of the speed mods, but I don't want to sacrifice the solid backwall. Comment? Suggestions?
