This comment by @JTizzle brings up something I’ve thought about. With side effects we can only add or remove mass at the axle (mass that doesn’t affect the rotational inertia), so it doesn’t make sense for yoyos with SEs to be designed with very much center weight. A rim weighted yoyo can be customised to have a lot of center weight as well, which will have a large effect on feel, but a center weighted yoyo will only be able to become an extremely center weighted yoyo. > [@One Drop YoYos Official News](https://forums.yoyoexpert.com/t/one-drop-yoyos-official-news/43021/3868): > > I did notice during design and testing that The Crucible changes significantly in feel with different side effects. My guess is since it’s so heavily rim weighted relative to the rest of the body, changing the ratio of weight towards the hub actually has a big impact, more than any other OD i have played (Summit 2 has a similar effect) --- _[View the full topic](https://forums.yoyoexpert.com/t/summit-2-unboxing-first-impressions/442245)._
