Congrats on the new boat - everyone loves getting something new!
I've generally gone by the book on daggers and not spent too much brain sweat on it. I noticed the US champions on a Tiger leaving their boards down all the time maybe six years ago...
There have been several threads on the issue with gybing and fixed board boats - do a quick search. My conclusion was and continues to be that the guy who wrote the manual on my boat has more time on the water and on the boat than me. If I can prove him wrong, I might try something different. I am secure in the knowledge that I am not an innovator - further, I am not averse to trying something new. It works for me.
