Hobbyman - 10-4 I am in the same boat!!
Hawkeyes - You probably don't have very rocky soil there in Iowa. If you do, IMO it is worth a little extra money to get the heavier pipe. Our soil is very rocky and the really thin stuff is VERY easy to kink and/or crush with a rock. I think I used 1.5" schedule 80. Downside is a 500' roll of schedule 80 is a bear to handle! Definitely a two man job!
