I just picked the DV888 because I’ve found it to be very reliable, and a simple shape. Lathing something like a Superstar would be pretty difficult, and the DV888 was the simplest one I had.
I’ve accounted for it being lightweight, so I was planning on giving it some heavy-duty rim weights like a Protostar (The rim weights make up at least a quarter of it’s overall weight, and a 32nd of it’s volume). The light-weight center and the heavy rims would give it a great rim-weight ratio, giving it godly stability. If the DV888 is too thin, I guess the largest yoyo I can think of is the Oxy Megatron, but I don’t have a reference model for that.
I probably could make a 2.5:1 POPStar, because those have really thick rims. They’re pretty hard to model though.
PS. I actually didn’t know that Luminator rim weights were rubber. I thought they were metal. Any suggestions for dark-steel (or something that looks like that) weight rings?
