Yeah I own a few summits myself. Being a bowhunter for many years with both compound as well as re-curve I found out the hard way about the rail more than once. Like not being able to get standing because ole ghost deer just suddenly popped outta nowhere!

coongitter, you need to practice sitting down shooting a lot as well. There are times that a whitetail will just suddenly be there like a ghost and you wont have the opportunity to stand. I've got a few trees in my yard that I climb up and practice from often in every position I can think of. Had a friend that thought I was plumb nuts for doing that until he saw me shoot a doe while dang near laying out sideways around my tree to get the shot off. She came in exactly backwards from what she usually did! I put my harness to use and let it support me while hanging out.

It does help to have a loving wife that will pull and send your arrows up
