Good question. Answer depends on too many factors though. I ordered a medium since I don't want to look through it but my situation is similar: bike is 500 miles away and my screen got hung up in shipping and I don't have it yet. After reading the post about raising the extra large, I'm wondering if the medium is too small. Then again, the gentleman who needed to raise the extra large WANTED to look through it. My only gripe with Mark is that there was no place on his website to track the shipment. I emailed him and he quickly replied though (supposed to be here today.....)
I was sent a USPS tracking # in separate email? I'll find out soon enough and report back. I just want to be not beat up by the wind, it's horrible here, most of the time. Even if I went full faceshield helmet, body still get's the abuse. Would like to see yours once you get setup!
