Working with PEX pipe

I bought a 100' roll/coil of 1/2" pex pipe at my local home improvement store for a basement bath. When I released the strapping holding the roll/coil together it stays coiled up and seems like it might be hard to work with that way. My question, Is there a secret to getting this pipe to "unwind" straighten out?

#1 Your going to need 3/4, not 1/2" for the main supplys all the way to the fixtures then step it down to 1/2.
100' of 1/2 could do a whole house or 2.
Make sure the pipe has time to warm up then bend it backwards as you take it off the roll.

PEX is easy to straighten, you simply warm the pipe up and uncoil it gently in reverse. Or you can run warm water through it to make it less stiff very quickly. I work with 300 foot lengths, simply uncoil what you need, straighten gently, then cut with a tubing cutter.

As to sizing, if you have a manifold system, you can probably use 1/2 inch for all the runs.
