Came scarily close to losing my favourite yoyo today :’(, so now my question is, what is the best yoyo holder available here at YYE?
Are you talking about a case or a single yoyo clip?
Case- any of the yoyoexpert size depending on how many yo-yos you need to store!
Single yoyo belt loop clip- I have the yoyofactory one and it works great for keeping your yoyo with you. However, it is exposed to being hit on things if you sit a lot
In the store, or in general? 
I like LegYoyo’s holsters. I have two different styles and they’re both very secure. From the store, nothing wrong with the YYF holster!
I have the same clip youre talking about, and while the yoyo is exposed a little, it is cheep and there arnt really any other clips that i’ve seen that protect a yoyo from being hit on things when you sit down. There really isnt a way to protect a yoyo from scuffs when dangling from a clip, unless the clip fully surounds the yoyo (more like a yoyo pouch), to me though that kinda ruins the idea of the clip, and I cant imagine a yoyo pouch clipped to your side would look very stylish either, unlike a clip which serves its purpose and looks stylin 
On the absurd side, ive been known to use thick leather cuffs as holsters sometimes. Wrap all the way around, caps still shown, and can even fit the superwide.
Only thing i worry about is something hitting the cap. Everything else is covered.
Haha a yoyo pouch would totally look like a robin hood bag of coins haha
I have the Tom Kuhn leather holster, and in my opinion it’s very stylish and cool, plus it protects your yoyo very well. I have mine slightly modified though, I took off the clip and put on a carabiner type clip. If you want I can PM you a link.
Braid some para cord and attach it to some clips along with a S-biner to clip onto anything you want. Plus para cord comes in handy whenever you want to pitch an emergency tent, or fishing. =)
