Glen and I and I think a couple others are using the mato's, they perform well. The set in my Tiger are very nicely 'broken in' and are very smooth and quiet.
I think the Asiatam sets are just as good, depends who you ask. The main difference is a ball bearing on the main drive shaft so I think that's pretty cool, although I've never seen one up close. As far as sprocket compatibility goes, again not sure.
Hate to say it but ask Phil at RCtankwars, haha
In your case, the Mato's will arrive much sooner!
