Thanks. Upon further research, it looks like the 24mm Seimitsu are my best bet- should fit where I need, come in the colors I want, and can insert artwork into them. Need them to go into a metal-over-wood CP, but I guess that is what routers are for....
As far as the Plasti-kote, I guess that stuff should stand up to use... a good back up plan I guess.
Kind of surprised no one sells the replacement shafts... I guess I technically could use two blue and two orange...
