I think the cement patches are great and have gotten many miles out of tubes with patches. I usually just change tubes when there are 3 or 4 patches. I almost always have a spare tube but try ot save it in case of major damage to one of the tubes that a patch won't fit, or I run out of patches (which has never happened).
16 patches is just getting started. The tube is hardly broken in by 16 patches. 25 or 30 is a good number of patches to aim for. After 30 patching just seems silly.
