The only possible problem with that, is the way you go about overseeing the work of the others as you go out to see how things are going. I'm guessing that you have a bit more tact than my old boss, but if the installer thinks that you're just trying to baby-sit them they might not appreciate it much, and you'll have a hard time hanging on to them. But if you use the time as a learning and teaching exercise instead of a lecture period things will go much better... My old boss.... well, I won't get into that.

Just be nice when you're there.

The upside to going out to each site is that you can see first-hand how each of your techs work and can more accurately judge who is worth more per hour than whom, and not just decide according to seniority and time spent with the company.(still being the new guy can start to rub you wrong if you if you do more/better work that the other guys and don't get paid as well.)
