I'd be a bit wary of jumping straight in and spending upwards of £300 on an Adventure screen. I'm 6'2" and my GS is also on order (no confirmed delivery date yet unfortunately - mid April quoted). I tried both the standard screen and an Adventure but frankly couldn't detect any significant difference. Admittedly I didn't have the time to 'tweak' the adjustment of the screen to any extent.
When my bike turns up I plan to see if the standard screen can be adjusted in conjunction with the seat height to achieve a resonable setting and maybe consider tobinators or a TT screen extender.
There is lots of info on alternative screens and adjustments elsewhere on this site. Try a search.
Good luck with it!
