Moguls - K2 Crossfires or RX8

Simple question. Which one of these skis will do better in the moguls for a level 6-7 skier?

I am trying to improve my mogulability.

RX8s are nice in bumps, RX9s are nicer.





(we're here to BUMP you up!)

I thought the RX9's are a stiffer ski.

What is better for moguls, stiffer or softer?

the rx9 are stiff, so my son greatly prefers his softer twintips in the bumps, while the rx9s are for ice and speed. but a good bump skier can ski on anything.

I think I found the main problem with my bump skiing and it is:

Just stiff enough that you can get pressure towards the tips to engage for the next turn, just soft enough that front/back balance is easy to maintain.

I expect pagamony's son is a bit lighter than I am.
