Enjoy the system, looks like it will provide a great ride.
Will have to wait until I replace oars to try it out.
I would contact pro loks and ask if he can make one with a larger ID/OD collar to fit over existing oar sleeves or wrap. Then next set of oars you buy, it would possible just to get the standard collars themselves if you are buying bare oars
I don't know why he doesn't offer this option --- a lot of folks already have the wrapped oars and they might want to try the new locks
I'm no metallurgist but I think the stainless shafts aren't going to bend or wear like brass oar locks.
Also the welds look strong. Spider you weld -- is the heat affected area on these shafts compromise the strength of the shaft?
