The neck is just too strange for most traditional players, but there is some logic/science to it... granted, if you wrap your hand around in a Hendrix Style, let's say, you might find it working against you.
I don't think I've played enough Strandbergs in my life to get used to the necks... but I could see it happening.
We can't expect one type of guitar to suit everyone and some styles benefit from more radical features. That's why we always need more guitars :)
