Were having our bathroom repiped with copper pipe and my question is which type of angle stops should be used? The person sweating the pipes put in 1\2" female copper fittings then a galv. close nipple then the 1\2" female angle stop and they all seem to leak. would it not have been better to use a 1\2" compression angle stop on the copper pipe instead?

Galvinized fittings???? You have got to be kidding!
Get the compression angle stops. I have only had one fail in 25 years.

Copper and galv. pipe will eat away at each other. Basic chemistry. The galv. nipples MUST come out.
Are you sure it's a galvanized close nipple? If so, it sounds like the plumber didn't have the right parts at hand and used whatever he happened to have with him. Never mix copper and galvanized.
My personal favorite way is to have the female fitting behind the wall (either copper or brass), then connect a 3" or 4" chrome plated brass nipple, then either a straight stop or angle stop, whatever you need. Use teflon tape on all threaded fittings. Put on a chrome escutchion, and you're all set, looks real nice.

The galv nipples ensure that the installer's son will have a job. Takes about 40 Years to disintegrate...

1/2" compression, Period. Never had one fail. Hmmmmmmm copper and galv. two different metals in contact with eachother, bad news. Electrolysis!!!

Behind the wall I like to use a cast bronze elbow with the ears on it, like this:

That elbow is nailed to blocking between the studs. You can crank on a nipple of whatever length you need, then crank on a angle stop, should be no problem with twisting.
