Yes, POC tempor with the clear visor. Didn't tape over the holes - haven't tested it as it's strictly not allowed and I'm actually not sure it's faster with the air channeling POC seems to have incorporated into the helmet. I guess it should be tested - if it proves faster I could try and hear if POC could make a helmet without the vents for me or maybe just fashion some official plugs to use (like the LG P-09).

ETA: Could be interesting to try some of your glasses to see if I could hold my head low for the optimal position for more of the time. Not sure what the UCI would think, but I don't think it's prohibited (but the commissaires could still give it a no-go if they felt like it I think).
