My Dad has one and I was thinking about using it this year. I have a summit Cobra X4, however I am wanting to try something that isnt open in the front. The API needs new shrink tubing on the chain but thats it, its barely been used. Have you or do you use one, if so give me the pros and cons. To me my summit is lighter and a lil easier to put on the tree but that is minor. Thanks...
