Ive used 2 small solo tent. First was a Gelhert Solo (some-one elses
review and pics here). Its very cheap and very small, insufficient headroom but I could fit a pannier under the fly each side.
For a longer tour I used Hilleberg Akto, a bit more room and still standing after some really harsh Atlantic storms with horizontal rain.
There is no single best solution. Tarps give no privacy in campgrounds and are useless in major storms. Tents are hard to pitch on rocky, rooty, steep woodland, hammocks need 2 trees.
