Standard or Double Bubble Screen?

[Huls]

I bought a cheap Chinese one off Ebay for about $20. Looks very similar to your pic. I figure if it's no good, I'd just buy another one. I still get buffeted on standard or double bouble, but the screens cause buffetting at different spots. The standard screen causes buffeting from the upper chest upwards and is a pain above $1.60. At $2.20 it's very uncomfortable and you don't want to go faster. The double bubble causes buffetting at a higher level (around my head) but the double bubble is definetly better at $1.60. Maybe you should buy a couple of different height cheap screens and test out which suits best. By the way I'm about 6'1".
