Since this years ET is a sintruded base, I concur.
It is pretty noodlerific outside of the park, but unless you are trying to set land speed records down the hill, or you are euro-carving a black run at speed, you will be ok. I wouldn't take it off any 50 footers or anything, but it's not horrible...And that's coming from someone that weighs 215lbs.
Never ridden a Banana or a Jussi, so I can't compare em.
Have you ridden an ET and airobic? if you have, is the flex difference huge between the two?
