Hi Dave
Don't give up on the idea yet.
I own a 10' Surf in 2 piece. The board was bought exclusively for travel. In this regard it works very well. In Europe the airlines have become stricter at enforcing weight and length criteria, using overages as an opportunity to charge. Some have even reduce length criteria to 2.5m or even 2m to generate more overage revenue.
As for the board itself. First is perception, surfers are pretty "traditional", resistance to change is evident on almost every beach to go to ; ). If you own 1, someone will comment.........
When it comes to how they surf, please believe my when I say great... A little heavier, a little stiffer in the mid section, but step back and for most of the time only the tail and rear section rail is engaged. In reality, after your 1st session it's just another board.
Now I accept that I don't own a high performance board and I'm not smashing the lip on double overhead. If that's what you have in mind then it has it's limitations. But for almost everything else I'm on a very capable board.
If the choice is to travel with a short board that's hard work and/or wave specific, inflatable or 2 piece. I know which I'd have

Hope that helps.
