I don’t really see the point of another summit if you don’t plan to compete with it
Get the cascade. It’s super fun and completely different from the feel of the summit.
If I had to choose between two yoyos and I already owned one of one of them I would definitely get the one I didn’t own yet. I do my best to get the exact colorway I want when I get a new yoyo (sometimes this is difficult and sometimes there is just more than 1 colorway I want) but I generally get more enjoyment out of trying a completely new yoyo than I do having an additional colorway of something since it is nearly guaranteed that all but 1 of that yoyo is just going to sit in a case.
Get a different yoyo then you already own. What is the fun in having 2 of the same unless you are honestly going to compete and need it… Or you doing any 3a soon? I know I sure as heck am not , that looks are as poo…
