I would suggest the Speed MP rewards a more compact swing, attacking tennis, with, yes, has a side-serve of control.
By comparison if I use my Rad MPs I have to flail away confidently on every shot, footwork be on point, employ deft assured touch at the net, and simply never backoff a serve.
The Speed MP is easier on all counts.
It has way more power, more dampening, more defensive forgiveness, and hits a magnificently hefty ball.
With the Rad I can get overpowered by an opponent more easily, with the Speed I return fire.
(But the Rad shines if it's your day, it is an absolute laser if that's what you are up to looking for? Plus it is a serving
NLAW.)
The Speed MP is not as manouverable as the Rad MP. That can be a positive in that its swing path is more predictable and bankable. This is the MP 360+ with the higher SW.
