Stock up on the batteries.
Duncan FHZ Pulse with a Terrapin X A+ Beefcake kit and spare clean bearings and a Duncan spacer kit so you can get that yoyo exactly where you want it. Oh, and an A-sized CBC CenterTrac.
Pair of Duncan Pulse loopers.
Extra Duncan light-up dice for 5A
Get a Shinwoo LED light-up kit if you can get them. Get two sets. Fits most yoyos. Gives you loads of options. Try a pair of white Unleashed!! Duncan Hayabusa clear(got the mod spacers too, it helps). Glue the light kit in place or the yoyo is gonna vibe like mad unless it can be wedged into position
Now, also get yourself a glowing DieNasty and a Magic YoYo D5 Sprite
If you’re modifying yoyos with the screw/nut axle system, MARK your nut and axle and yoyo so you can put the yoyo back together QUICKLY with minimal vibe. Don’t use a Sharpie for final marking, use a file and cut very small notches because ink will quickly fade.
If you want, try to get a solid colored Chief if you can, and get the glow mod kits. The kits work good in other stuff too, but I find the CLYW with the “Chief rings” ideally fit them. Otherwise, use the adapter tube to make them fit. Clear plastic yoyos also work good as the light kinda looks like it’s going into the plastic when spinning. A clear DM2 would be awesome but really, any clear yoyo with removable caps would be fine.
Why not: Go nuts and bulk up on glow string!
Learn diabolo, there are light-up kits available here as well.
