Question
QUESTION: Hi Matt,
I am researching the options to install a sprinkler system for my home. I live in Wisconsin and would like to know the pros-cons of the auto-drain install Vs the type that needs to be winterized using pressured air blowout. Also, is there a longevity/reliability advice between rainbird or hunter heads.
Appreciate your advice - thanks!

ANSWER: Thanks for your question.
I live and work in Michigan so I'm experienced with winter and it's effect on sprinklers systems. Personally I don't install auto drain systems. I have to warranty my work and I'm not comfortable with a self draining system. They do work, if you install enough of them in the right places. The problem is, the way you find out you didn't install enough is when something freezes. For me thats a free service call and a negative mark on my reputation.
Rainbird vs. Hunter. Well, I have to be careful here, I use both. Hunter rotor sprinklers (PGP)are my chosen medium turf sprinkler. Rainbirds rotors work OK, but I have 0 problems with the Hunters. They pop-up, rotate, and go down for many years. Pop-up spray sprinklers are an even match. Rainbird's 1800 series and Hunters PROS series preform equally. Either is a good choice. Valves again are an almost even match, but I 'll give a slight advantage to  Rainbird's DV-100 valve. They last forever, I think.
Controllers, well, that's like recommending a haircut to someone. What works for you doesn't work for another. Both company's have good controllers and you need to decide what features you want and what you can afford. I usually use a mid grade controller for residential applications. It has enough "bell and whistle" and yet can be operated by most everyone.
Hope this answers you questions.

QUESTION: Hi Matt,
I am Presently meeting with installers to put in a system. Any  specific areas I should 'make sure' I address in the contract/warranty - Thanks!

Answer
Sorry for the late reply.
As in any product or service, price is not the only factor. For the most part you get what you pay for. Be cautious of a "too good to be real". A simple formula I recommend is divide the price by the number of sprinklers. It certainly isn't fool proof, but it at least give you an average price.
If most contractors are quoting 7 valves and someone quote 4, avoid that person. They're guessing. The same goes for sprinklers.
Has the contractor been in business for at least few years?
Does he have insurance? (ask for a current certificate)
Does he have references?
Who pays if he cuts your phone line?
What completion date will he guarantee? (have this date on the contract)
Does he provide an as-built plan or sketch?
More than anything, trust your gut instinct. Do "YOU" feel comfortable with this person. Unlike most contracting, irrigation is a long time commitment with this person. You should feel comfortable dealing with them.
good luck,

Matt
