If we could only have ONE, and be 100% convinced it was a do-all, best-of-anything product, neither you or I would have a bunch of shields laying around from the LAST bike!!! (I still have five from the long-gone Yami here in my home office!)
I suppose an F4 would be nice, but for me, the ticket price for that ride is $425.00 (didn't go any further than that so I couldn't tell ya if shipping was included or not)
