HI brett,
In my current situation, I am glad I kept my .40VFs! We have a few PAs, but they will still be a while before any new ones are made.. I haven't used a RoJett, but that's just because I have only bought one "new" PA! If I could find a good used Ro Jett at a reasonable (to me) price, I would try one.
I hope to rebuild my 1996 NATS plane and it used a .40VF, so it will again.
Bill
