I was a happy Laminar Lip customer on my '04. Unfortunately, during a trip last year that may or may not have included some stretches of high air velocities (ahem....) it flew off on the interstate and I had no easy way to retrieve it. I thought about buying another, but my original stock windscreen was looking yellowed and pitted from age. I decided to give the V-Stream a try and I am really happy with it. It provides much more (sometimes too much) wind protection, which is particularly nice when riding in cool weather. I find that the air flow over / around it is smooth and I don't have any of the buffeting that I used to experience with the stock windscreen (without the Laminar Lip). The LL also did a great job in smoothing the air flow, and I was never bothered by the "add on" appearance. If my stock windscreen was clearer, I probably would have gone back to another Laminar Lip. Having the nice, clear V-Stream has been working well though. I guess I would be happy to endorse either option.
On another note, I had also considered a Puig clip on - my son had used on successfully on his FZ6, but ultimately, the V-Stream seemed to be the right choice for me.
Good luck!
