Yes, you should be using "limiting speed" with MMTTY.

It is slower but not excessively slow considering that the
alternative is a major problem (early PTT drop, buffer
issues, etc.) for FSK users.

"Longer time to get through each contact" is only a
factor if you are running and never have to call CQ
more than once. If you don't have someone tail-ending
every QSO, the time to complete a QSO is no longer a
limiting factor as you have "slack" time.
