If it is the standard BT one then change it to a Hicks teflon slide that will give you more clearence and you should be then able to shoot cock vane up.
Yes it is the standard BT cable slide.
Can I get the one you mention from Lancaster? If so....(and bear with me....lol) will pulling my cables to the side (even as slight as this may be) effect the "level" of my arrow (raise or lower my nocking point)?
