Anyone else here use the Mantis arrow rest that came with your package?
If so and you are getting unexpected flyers once in awhile or not so tight arrow groupings I may have a cure. After shooting many arrows and driving myself nuts playing with the horizontal adjustment on my sight pins and cursing what I thought was just bad shooting form, I decided to take a good look at the rest. What I noticed was the little trap door rubber thing that allows you to load the arrow was hitting my vane. Maybe with slimmer arrows this wouldn't be an issue but I'm shooting 2215's and the blazer vane had left coloring all over the trap door. Since it doesn't really do anything I just clipped it off.......my arrow groups were instantly much better and hitting where I pointed them. Not sure this is the best arrow rest anyway and I may change it but I thought other users may be able to use this information. I'm pretty sure Martin includes the Mantis with all it's RTH packages.
