I have cointakers in my Jurassic Park and my Roller Coaster Tycoon. I bought a kit for the RCT and it uses supers which overall is just a little too bright especially in the GI. The Jurassic Park was pieced together and I like it better. I used supers on the 2 jackpot inserts, frosted color for color inserts and cool white frosted for the GI.
I'm not a huge fan of colored bulbs for GI, but on some it looks ok. I think you're better off making your own kit. If you email cointaker they will send you their map of the game with what leds they use for each then you can tailor it how you like it.
I bought a bunch of frosted leds from pinball life and they are nowhere near bright enough, haven't tried the others.
