Don't know of one of them adjustable spoilers for an ST. What are you trying to do with it?
I'm an average height for a bloke in the UK at 5' 9", but I manage this by having the cunning plan of having an above average body length to offset my less than average short stumpy legs - or to put it like my grandad "Yer a short leg un, long back un". All this means that, like John Wayne, I sit pretty tall in the saddle, while still having to be on tiptoes to reach the ground.
Sitting tall puts my lid into turbulent air on the ST and my head waggles around like the Churchill dog with a standard screen. I can't stand the sight of the higher touring kits, but I have had good luck cutting the standard screen down a bit, seems to lower the point where the air is turbulent, and put's my bonce into a clean airstream - increases the wind blast a bit, but cuts the turbulence so I can keep my head still.
I am 6' 2" and found the STD screen a bit short, and as you put it "my head waggles around like the Churchill dog" so I was after something a bit higher, I know they spoil the look, but comfort can come at a price sometimes.
Bikes: R1200RT F800GS. Hopefully another Ducati soon

Im 6ft tall, my fixed height touring screen I bought of someone on here, (might have been Jools) has Zero Gravity on it and from memory is about 2" higher than the standard fitted to my ST4. I have no problem touring at 80/90 on Motorways for long distances
