Schneider Team Drivers -Please Advise.

Hi,
I am thinking about driving team (reefer or tanker) with SNI. Never did this before. I have my A with hazmat and tanker. I live in NJ and I am a new driver but would be coming in with an experienced driver. My questions are:
I hear SNI is a good company to "start off with" This gives me the impression they are not the best to continue on with. Why?
How is the pay. What can we expect to each gross per year. Do teams drive all states or sections depending on where you live.
How many days off do you really get each week? How many miles per week do you drive? I am under the impression that team tanker drivers with twic and hazmat are the highest paid. Is this true? Both of us have twic and hazmat. Not sure if I want tanker or trailer at this point. I would love to hear your experience with this company please include how long you have been with them. Thanks for your reply, Susan
