Personally, I don't like Zan tips at all. When I was going through Mezz shafts, prior to buying my Vigus, I ended up removing them every time (Hybrid pro, Hybrid pro 2, Expro... tried just about every Mezz shaft). In fact, the ILC shaft I now use on my Mezz for Chinese-8 has a Searing tip, and I hate to say it with the bad press aimed that way (and for good reason from my readings here), it does play really well.
My other Mezz shafts I switched out for Longoni Fuji tips which I was gifted. They play lovely, but are also overpriced... I only have the ExPro shaft now, and it's a backup to the Vigus which is my 'forever' cue.
The Musashi Shaft I use on my Vigus right now came with a Moori Medium which, to its credit and my surprise, has played fantastic from the first hit.
I like Mike Wooldridge tips, and will go back to them when change is needed.
I heard good things about Thoroughbred tips from someone on the forum, but when I tried to add their rep on WeChat, he never accepted it....
