The MT3 profile is a very interesting one indeed, however there are some factors that don't make it as easy of a choice as SA
#1 Massdrop owns the tooling, any MT3 set will have to be a drop on their store.
#2 Doubleshot tooling is still being created for the recent Susuwatari set from matt3o, and the font chosen might not be everyone's choice for new sets.
#3 Due to #1, the time to get the set to GB phase could take easily just as long as the current SP SA production schedule is.
