What is the best type (single, dual, or doublesided-cant think of it all of a sudden) and what lense, rocks, and so forth should i use. Is there a certain place to find the parts needed? my saber currently does 8-27 and 4-24

I'm a purist so I always play a single-hilt saber. I use this as my best lightsaber combo (for lightside):

Expert Fencer Emitter
Ultimate Diatum Energy Cell
Pontite Lens
Solari Crystal
Upari Crysal
Violet Color Crystal.

For my darkside character, I use the same as above but replace Solari with Qixoni crystal (the one you get from Onderon) and Red color crystal.
