I vote for a collar & a border patrol handle, or finger grips or SFG.
The way I view it is if you are going to use a option on spacers go big or as The Captain put it, "either red or black fiber insulators".

Or for the those liking a butt Cap.
Nickel silver butt All Black spacers, SFG, Finger grips or border Patrol handle.
