I have always drilled the holes for big threads just like this to be as =
close to the shank diameter as possible without going over. Too small =
and you risk splitting the wood and losing a ton of grip. All 200#s of =
me has been able to hang from each one as long as I can hold myself up =
there and it has laughed at me. Two would be fine. You are roughly =
10,000 times more likely to drop it during removal/stowage. Have a =
backup plan (bungees? net?) for when it happens then.
