It just seems that about once per month there is a similar post. And often the poster says something like "a few guys on my team have them and they are really awesome." 1) if you have had them on your hand and they are awesome, no need to ask here, and 2) as often as this happens, it makes me wonder if the poster asking has a vested interest and is trying to market the brand through the post. And no one on the forum likes to feel like they are being played.
You may be genuinely asking a legit question, but this is what you are jumping into.
I have not heard of MTZ. I have seen some decent Mexican gloves and some garbage. So hard to know.
