I guess I'm a "Nazi" too...I have a serious collection of Arai RX7RR3's-4's, HJC's (02 models), Shoei's, Bieffe's and now an OGK from Japan. I've track crashed in lessor helmets and still have memory issues...what was I saying?
Buy the best lid you can afford...end of story!
I always cringe when I hear my students come in to tell me about their $29,000 Aprilia Mille, $25,000 Ducati 998-999, $50,000 Harley Road King or whatever...I ask them how much they spent on gear..."I bought some used gear through the Bargin Finder"...or..."it's all the same so I bought a $49.00 lid from storeX", or my fave..."I don't plan on crashing and I'm buying loud pipes...that's better than riding gear!".
If you can afford the spankiest new duck, prilia, gixxer, kawi, or hog...why not fork out a little for a great fitting lid and some protective gear...even motorcycle specific boots make a huge difference, oh yes...right, I forgot...nice pipes!
Take care all!
