The main problem I've found with the Evoline is getting the chin guard to latch properly if I decide to put it down(full face mode) while riding. Pushing the guard back with one hand pushes the helmet all over the place, making it uncomfy at best and, if you wear specs, causes them to sit in the wrong place. Not easy to sort out with one hand.
Other problem is that the weight of the guard when folded back over the lid causes headache pain on my forehead after about an hour or so of riding. The weight seems to pull the front of the helmet tighter at the front. No issues with turbulence behind my RT screen.
What version of the Evoline do you have? The later Evoline 3 is lighter and I have not had the issues you have had with mine.
