Well this is also something I have been toying around with- I try to tee it up high- silver/orange castle tee height to get that hitting up feeling.... near the end of the summer that was going quite well but when I started skying a lot went back down to pink castles but generally try to stay at the higher height.
That sort of confirms my thought that you are likely to be hitting down on the ball - which adds (lots of) spin! If that's the case, then it's much better to fix that than to kludge things with a different shaft. If the Diamana is the Blue, then that's a nice mid launch/spin one, so shouldn't balloon! The Red is higher Launch/Spin, but not ludicrously so.
I'd suggest you try using the longest wooden tees you can find (only just put in the ground) and try to ensure that you hit up on the ball! - even almost trying to skim the grass about a foot behind the ball! Make sure the ball is just inside the heel of your front foot at setup.
