WARNING: It gets very loud during the first 30 seconds of the video. Turn down the volume or risk having your ears bleed. 
Luckily for me, these Synergy Caps cause absolutely no wobble or vibe. Hip hip hooray!
Oh, and I got a new trick I wanted to show. Tutorial coming soon…
They are awfully loud. 
Yeah, sorry 'bout that. I shouldn’t have brought my DM that close to the camera.
It’s just that the caps sound like a dying cow. In my opinion.
Nice vid ;D
I think tyou should cut your strings, its really long 
Hmm… Now that I think about it, the strings are a bit long. I didn’t even notice since I just automatically assumed they were the same length as my cotton string(which is the perfect length for me). Thanks!
“REEEEAUUUUUUUUUUUUUUUU–” 
They look really cool. Did you notice anything different with the way your yoyo plays when you put them in? I’d imagine they made it a little heavier.
Good thing my volume was only halfway max when I watched it. I didn’t read your entire post before watching it…
