Ive been to WDW twice on my ST4s now and the bike was always much better than I was!
Ive still not found a screen I'm 100% happy with - I have the Ducati touring upper fairing and screen now & I only rate it as average.
Standard screen with a Laminar Lip http://www.laminarlip.com/
is the most comfy Ive tried but a hi-rise screen can work well, I like http://www.zerogravity-racing.com/
Here are some bar risers from a great guy in Ireland: http://www.ebay.co.uk/itm/DUCATI-BAR...-/262142775469
So you can fit 50mm clip ons.
or you can fit riser plates under your existing clipons.
Ive raised my bars a CRAZY amount, careful cable routing and longer brake hoses are needed the only problem at the 75mm extra height I have is that the choke cable cannot work - a longer cable might work but, Ive not sussed that out yet...
