I use an aid for my Excalibur, not because I can't draw it back, but because it always draws back straight without rolling the string or going off center.
Up here x-bows are allowed for everyone in the archery season, I don't really understand all the argueing that goes on about them, I think most people do like me; use it untill your good enough with the new compound to hunt ethically. Anyways, I'm glad x-bows are legal, I bought one to take advantage of the longer season and found out how big and cumbersome it is, I probably wouldn't have been introduced to archery if it wasn't for the x-bow.
