I have been stringing my own frames for a couple of years without a problem but am considering buying an Ozone Pro Tour and have heard some horror stories re: stringing frames with O-Ports. I did a search and have seen mention of boomerangs, inserting holes, hard grommets, locking turntable, etc. and simply want to know how simple it is to string these frames and if I will need extra tools or training to make it happen. I really enjoyed hitting with this frame over the past couple of weeks but have concerns re: stringing them at home. Thanks for any advice!
