I don' t have a Summit it, but I' m working on it. lol I DO however have a Bear River climber Myles Keller endorsed model or something like that, but I love it. It isn' t the sit/stand style, it' s a hand climber, but I love it because there' s NO rails to worry about when it comes to shooting. Just another opinion though, so go with what feels right! Cheers!
