I'll just add that I find patch kits useless on the road. Most of the expert articles I've read say the cure time on those patches is 24hrs, and that's been my experience. A patched tire will get me about a mile or two further down the road, and I'll have a flat again. So, I say carry a replacement tube, and save the patching for when you get back to the ranch, and let it set-up overnight.
