Hey gun you do have a big gap between the BW and Rayzr. A midnight vibe or backlash is needed. My arsenal is going to be similar to your. My BW solid is fairly new and its my benchmark ball for me. So a Plague, Trap, BW, Vibe/Bl, and Rayzr makes sense to me. Just depends on layouts and surface changes you make to each ball.
