RE: NP on RDM ?
Thanks Happy for adding an important point that I forgot. I indeed use the Hot Rods and one NP skinny on recommendation from NP and HSM. I was told that some skinnys like the Powerex are either too soft or have a curve that is not as compatible.
Unlike jaume I rigged NP up to 7.7 Spirits and now SuperFreaks up to 8.0 on my skinnys with excellent results and my 9.0SF with acceptable results, but that could be because of the brand of masts. Because of my concern with a skinny being too soft for my 83 kg, i have stayed away from extenders or long extensions and instead gone all the way to a 490 Hot Rod.
I hope that clarifies.
