Thank you to everyone who has posted on this thread i really appreciate it. I am going to keep reading and see if I can get this all nailed down. Cobra IMO that lawn looks amazing I can set my irrigation to any time that is needed i am not concerned about that. What i am concerned about is if i should use the aeration technique of seeding or slice seeder. My local true value has both so i can rent either one of them. I do not want to sound pig headed but all things considered money is not the most important factor. I spend my off days outside all day perfecting my yard I just want the best damn yard on the block.
