James: As I posted in one of the other forums on here, the Lip does what it's supposed to do......but only if you're ~5'9" or shorter. We taller guys get the remaining wind right in the face or top of the helmet, depending on how tall you are. It's a simple attachment method with really fancy 3M velcro pads and they even give you an extra set so you can put the lip on another bike if you want to......or if your original stock screen gets smacked and you need a new one. Sure I'll send you more pics if you like. Send me a PM with your email addy in it and I'll send 'em off to you ASAP.
Re: BC trip. The real trick is to take about 5 days minimum. That seems to work out the best, at least for me. I also want to tackle the Duffey Lake Road (BC#99) from Lillooet down to Pemberton this year. Buddies of mine have ridden it and say it's also very challenging. Evidently you may have to carry gas.....Well, we'll see what the summer holds in store....
