Versions of a finger spin dimple SE have been tried and ruled out:
I’m not quite picturing what shape would cause this hazard more than a UL. I think versions that are better than ULs but still not great by the standards of FS yo-yo hubs could work. Something like a Flat Cap with a concave?
Shape assortment packs would be awesome too! You could sell specific colors or do titanium or brass sets. I would also really like to see some side effects with a pyramatte finish. I guess they would have to put them in some sort of fixture to protect the important parts while they tumble them, though. It would be nice to have a matching finish, especially with a single color yoyo. I think a weight tuning set could be kept as simple as possible, which is why I suggested Flat Caps. It’s a simple cylinder with a flat top. You already have a 2.5 gram Ultra Light, and you can just tweak the height of the Flat Cap to adjust weight on the others. I think even at 9.5 grams of aluminum, they wouldn’t be too ridiculously tall, besides, they are more of a learning tool than a style choice. Put a simple clear anodizing on them and a simple number engraving on the end for the weight.
Remember that Anti-Yos are 4.7g, compared to Ultralights which are 2.5g and do not protrude from the hub. So all of the protruding material in the Anti-Yos contributes 2.2g, meaning they’d need to protrude by roughly 3.2× that much in order to be 9.5g. I’m pretty sure that would make them about as long as stunt pegs.
We’re talking about 8 at retail, not 100 at wholesale. If you pay for them to machine 100 for you, then there’s zero risk for them because they get payment up-front and it’s your job to sell them, so there’s no retail overhead. One Drop have never had overly high quantities of any one Side Effect available at once, and yet there are always various designs & colours in stock, which gives me the impression that Side Effects also don’t sell very quickly.
ngl my brainier is one i get endless joy from and it makes me auto-smile every time i pick it up. of the handful of od’s i have it’s the one I’d never consider selling cuz i know I’d miss it instantly
