DIY sprinkler question (please help!)

I live in a frigid climate and am going to be using poly pipe for my irrigation system but reading through some irrigation manuals it says NOT to use poly when going from the main line to the valve manifold (due to rupture). I will have a plumber come and install the necessary equipment into the basement (shutoffs, fittings, etc...) all the way until the backflow preventer, then I will install copper pipe down into the ground and couple that to 1" poly and make my run to my 1st valve manifold ( I will have 2 manifolds and 4 valves). Will this be alright? If not, what do I use? When installing my valves on my mainline, should I tee off the main line a foot and then install my manifolds or can I install the manifolds on the main and continue to my next valve? Sorry if this sounds stupid and thanks for any and all info!

One thing you should plan on adding is compressed air couplings. With them you can pay chimp change to have folks with big compressors come once a year and blow all the water out of your system. No water or moisture. No freezing problems.
