Doesn't really matter what anyone else prefers. You'll be using the rod, get it built as you please.
You'll find the standard configuration is a long front section / reel seat/ shorter rear section. For example, 14" front cork, 4-5" reel seat, 5" rear cork.
When getting rods built or modified I found it very helpful to search for pics of what I'd like my rod to look like. It also helps if you can physically hold some rods and see what feels best for you.
