Hey Fred, well I do have a flexfire 6'2" which I don't use often simply cause I didn't find it was the right board for me. My day to day board is the Spitfire leaving the Hellfire for when it gets better.
The flex fire is of course easier to duck dive but the Hellfire gives me that high performance end with all the benefits of a hybrid.
On the other hand the Hellfire is not hard to duck dive at all. It's a very good board and I think you will be VERY happy with it
