I'm going to add a standard (non-supportive) vang soon and I was wondering what the best way to attach the block at the mast would be. We have an un-used bail on the boom 1/3 of the way back from the gooseneck that will work for the vang. At the mast I could either use a padeye or a pole ring. The pole ring looks stronger; we had a padeye rip out in a mildly uncontrolled gybe (preventers are going on soon also).
I was considering the Ronstan RF41 if it has the right radius to fit the mast.
