RE: How to remove the integrated roll
If your married to the hook, all you have to do is temporarily remove the shaft to take off the brass rollers or sheeves and reinstall the shaft so that you can ultimately hook onto the shaft. However, the one thing that is hard to discern is whether the shaft is robust enough to handle downhaul forces over the long run. North seems to be suggesting that their design is up for the job, with or without the rollers in place. Really, only time will tell. In any case, you don't have to be unhappy.
