Howard, dont joke about cornering JB or any of the iQuad crowd, go and DO it. Unless they are REAL busy they will give you time.
Go and see Ben from Rev, I am sure he will help you out.
You could probably walk up to anyone who is actually flying a Rev they own and they will happily give you a go on the handles. Dont forget some of the folks who are flying Revs will be doing exactly what you should be doing, getting the cance to talk with folks who know more than thaey do. And trying out different Revs.
And yes, there is a new Rev on the way out, specially designed for light wind work.
As I think I said B4, the cheapest way to get a lighter wind Rev is get another rod set for your EXP, I am fairly sure a Race set would fit it fine.
Mate if you come away from the Fest without at least talking to JB, iQuad, Ben, Watty and SO many other folks you will have missed a BIG oppertunity. GO for it my friend. You will not regret it.
