Has anyone compared the SRF against a Cardboard Wave

It appears a similar concept, I found the wave felt a bit large for a twin tip, great upwind, good through chop etc. it probably didn't carve as well as I expected but still good (i had to play around with the foot pad placement but havent experimented with the fin set up. ie standard thruster set up rear with the standard twin tip fins up front.) In fairness it is a style of mutant not a twin tip
I am thinking the 140 SRF would be a pretty good but may be power hungry.
(always a compromise)
Does anyone have demos in Sydney
