In my opinion different methods of legends don't look good together. When I use dye sub PBT RGB it is with my dye sub sets, and same with my double shot RGB sets. Then again I normally only use specialty caps on escape and that is it, most of my novelty caps just sit in containers which is why I started giving them away to people when they buy other stuff from me.
If this were done I'd say all one method, and dye subbed PBT would have the most detail but the colors would be inaccurate (no red or yellow on black) or the UV method would look pretty awesome.
