The question was answered. And some of them are subjective. I find hydros infinitely easier to setup (most systems come prebuilt), and repair is on par with mechs. most people seem to fear hydros especially on the repair side, but seriously if you have any mechanical ability at all, and can read instructions, its easy money.
If a hydro blows on the trail, then it will stop working. Same with mechs. If you carry the "spares" around for the mechs the "spares" for hydros aren't that much more difficult to carry. It is messier
Otherwise I would agree.
