Greg, they make one called an SL, I believe... it stands for side load, so obviously it allows access from the side. Might be something to look at if that's a concern of yours and you wanna try one.
Thats the one I bought also because I did not want to load a broadhead tipped arrow from the back. It just pops in like side load wisker bisquit. It is indeed called the Twister Safari SL. I don't see it on the apa website this year, I think they may have dropped it for 2006. For those who can't quite grasp how it works they have some photos of it in action. Try
