Xlab Carbon Wing hydration system

Anyone own this in the link above / thread title? If so, how do you like it?

Btw, this would be going on my road bike (carbon seat post & Terry Butterfly Tri-Gel saddle w/Vanox rails). I'm not a tri / bike gal.

Training for my first century and am struggling on where to stop for water refills on longer rides in my rual area. I have two carbon side loader cages on my smaller frame that fits 2 large bottles now. Plus still need a place to do 'something' with the flat supplies etc.

This would be in addition to what hydration I have now. I thought about using my mtb CamelBak. But, my back is sensitive to weight (back issues) the only way I tolerate wearing it mtb is that the ride time is much less than road. Greater varied position too mtb.

It seems like over-kill on my road bike. But, I've run outta water before. Not fun.

Any other ideas /thoughts, I'm open.
