Some more observations:
1. Cut down and in the low position my head is in clear air but its noisy in my Tour-X. But there's no buffeting. Its noisy from 40mp up. The wind force at speed is quite severe but ok. Tested to 110mph with a Tour-X is a fair test. It would be tiring for any distance.
2. In the high position its less nosiy at low speed, maybe a little less blast at higher speeds. Its subtle.
3. But....In both positions I feel like Im riding a bike again and not in a conservatory, as Joker put it. For back roads I much prefer it and I feel I'm out there in the air. You'll know what I mean I expect.
4. Because of the noise, I wondered if I had created turbulent air. So I went back out for a blast with no screen. Noise slightly different, seems not as bad at low speed (30-40) but at high speed didnt it kick in. And the blast

. So even cut down my screen does 'something'. I dont remember any naked bike this bad. V odd.
5. Because of 4 above I would have serious doubts about the Wunderlich flowscreen at any road speeds. Perhaps an off-road gadget?
6. The best solution for me is probably a cut down for low speeds and a normal screen for my distance travels. TBH Ive always thought my Tour-X quiet with a normal screen, probably as Im not tall.
Anyhow, hope thats useful for somebody together with Jokers info.
Am I pleased I did it? Yes I am. Just for the looks and the feel on the back roads riding, which is where I want to be riding
