Yes, they will keep the bow consistant and stop that string pinch with that particular bow as well as make it much easier to ****. The standard rope and deluxe rope work exactly the same...the deluxe has rollers so it does not scratch up the rail as easily. The Sidewinder will only be needed if you are not physicaly able to use the rope aids which it sounds like you are. There is no diferance in accuracy between those three aids...
