Radio oprions 4PL vs 3PM-X

[RBX]

Will be trying some club racing this summer so im in the market for a new transmitter.

My question turns around the futaba 3PMX vs 4PL..

Things i like about the 4PL 2.4ghz fhss:

-It has the "speed" option for steering and throttle.

-FHSS receivers are inexpensive.


Things i like about the 3PM-X

-It has the FASST feature.

-So should i go with the FASST feature(less interterference) of the 3pm-x BUT i loose the "speed" fonction


So bottom line is it worth loosing the FASST feature in exchange for the "speed function" ?
