CAFS for Interior Attack lines (Residential vs. Commercial)

I am interested in some very specific information:
1- what gpm are you running on 1 3/4" and 2 1/2" interior attack lines?
2- do you restrict those lines from being "dried up" by the pump operator. Meaning that if he/she is flowing a 2 1/2" and 1 3/4" interior attack line how do you compensate and adjust those lines?
3- do you have any policies, rules, sop's regarding not using CAFS on interior fires that do not have carpeted or floors covered with some other "absorbant" material?
4- do you use CAFS differently for your city vs. rural stations?

Thanks

We are just implementing CAFS in our department and I would be very interested in the answers you get as well.

1. With our system (Hale) running at 120psi gives us 120 gpm through a 1.75" line and 160 through a 2".
2. Since our system pumps the same finished foam through all CAFS capable lines we are forbidding the practice of drying the foam if crews are engaged in the interior.
3. No
4. No
