yes ... I take a 14, 15 and 16 with me when I am on a big trip.
I use the 16s on the asphalt bits. 15s for most of the gravel and flat off road stuff and only change down to the 14 for much more intense stuff.
The bike hoots along the highway with a 16T. Across Europe I find myself able to sit on 80mph (by GPS), about 87 or so by speedo, for 8 - 10 hours a day, every day.
If you are going to put in an order at Talon and pay for p&p anyway, its just as easy to order a couple of different sizes I find.
