I have the older versions and could offer a suggestion (Pardon my ignorance if it's been addressed in the newer versions).
The counter bored bolt holes hold water, which is somewhat annoying to me. I plan on drilling drain holes out one side next time I have them off the boat. The annoying thing to me is the NRS ubolts are SS bolts with zinc nuts and washers, so sitting in water all the time = rust. Mine have been installed since october and half are all rusty and look like crap. I have a bunch of SS nylock nuts and washers that I'll be replacing all the zinc hardware with someday when I have nothing else to do...
