Assuming under-ground installs:
On LOOONNNGGG Pulls (100+ ft), I recommend using the largest pipe practical, usually 2" to 3".
The best thing to do, is dig the trench and lay the pipe yourself, then you'll have less than 360º of bends to contend with and your "targets" will be as close as practical. Let the excavators do it, and who knows what you'll end up with.
In fact, most of my advice centers around:
If ya want the job done right, do it yourself.
