I had originally posted suggestions for a front rest. From the few responses I believe buying the Shadetree joystick top and a base are the way to go on a budget. I see many use the Bald Eagle. However you can only use the slingshot due to joystick hitting the rear leg screw?? Is that the case? Is a Sinclair Heavy Varmint a better choice? Is a speed screw necessary with a joystick top? All help is appreciated. Thanks
