Rfy adjustable shock???

[Louis Angel]

I have never been happy with the factory shock on my little scooter.
(Genuine RoughHouse RH50)
It is adjustable, but even on it's softest setting it rides, well, ROUGH!
VEEEEEEEERRRRY stiff shock.

I am curious if anyone here has the RFY adjustable shock.

If so, good/bad? soft riding?

If anyone knows of a good soft riding rear shock, that would be great.
I know rider weight makes a huge difference on rear shock stiffness.
I am a very lightweight guy at 165 lbs. So it would help to know if you are close to my weight as well.
A buddy of mine who also has a RoughHouse50 said his stock shock was too SOFT and turned it up to max and is happy with it. But he also weighs 240 lbs. That is a BIG (no pun intended) difference.
