I recently got a steal on a VQ .46 size mustang but only to find out later that it has no retracts just standard solid gear. I was probably going to put air retracts in it anyways but I was hoping it had the mechanicals just in case I decided to save some money. Has anyone else had this problem? If not, what retracts, air or mechanical do you suggest I use? I'm thinking Robart 605HD for air. That might be overkill. Perhaps 100 series spring airs.
