Hayabusa Stick + 2lb Spring. Do I need larger actuator?

First things first: Hi SRK community! I'm new here! Image may be NSFW.
Clik here to view.

So I got myself a nice Hori RAP 4 Kai and ordered some nice goodies to mod the stick:

2lb spring
Octogonal Restrictor Plate
Start Button
Face buttons
Stick bubbletop

I didn't think/know about a larger actuator and reading online I kind of regret not having ordered it.

Is the bigger actuator "a must"?
