I put mine on last week and LOVE them, wifey does too, except she's banged her shin a time or two since they tend to be a bit slick on top. I bought this safety tape at Lowes today, $3.87 for an 8 strip pack. It's the perfect size for two strips per bar and nearly invisible.
As far as those troublesome bolt holes, I pre-threaded all the bolts with NAPA anti-seize and they all went in fine. I ran them all the way in, then out, before doing the install. A pair of 5 gallon paint buckets worked perfect for holding them up.
