yyj synergy caps

I want to get these for my darkmagic2. are they any good? how long do they spin?
I wanted to try this before I try something like a g5.

Gimmick. Not worth it in my opinion.

I only found 2 use for mine so far:

  1. pull start - may look impressive, and you can jump into tricks after releasing the yoyo
  2. catching the yoyo in mid air - harder than it sounds, I only really tried from a 1/2 mount suicide

Without trying too hard the yoyo can spin for about a minute.

I’m not sure if I can post youtube links but here goes: http://www.youtube.com/watch?v=PyuK4IZ_KCo

I had synergies but sold em they got kinda boring after a while but they are really fun at first
