I have to say, the service from Wingstuff was OUTSTANDING on this order! I called Wednesday around noon and discussed my order with Cameron. He explained how he installed the J&M Elite headset and also how he could use the better, thicker speakers than he could with the Nolan helmets. With my bike arriving the next day, I really wanted my helmets before the weekend. Fortunately, Cameron was able to configure the helmets and get my order shipped that same day! Thursday morning, UPS was at my doorstep!!!
I would highly recommend having Wingstuff handle the headset install on this helmet. To do it right requires drilling a hole and who knows what else. The microphone is a boom mic and it stays in position for both the open face and closed helmet configurations. Very nice mic, you can't even tell it's there when you're wearing the helmet.
As for the helmets, of course they're much heavier than a pure open face helmet and probably a bit heavier than a straight closed helmet, but being able to have both in one helmet makes it worth it IMO.
If you're at all close to the size boundary, then I would recommend going up to the next size up. Both my wife and I are around 23" and XL was snug on both of us. Hopefully Shark will come out with a 2XL soon for those with larger heads, not to mention more colors.
