Ben- I don't see on the data sheet where it requires baffles on the back side of the SD heads, can you point me in the right direction?

If you go down the sides of the hip with SDs and then backfill with APs you have to install baffles on the backside of the SD. Your best bet is just to always use APs across the entire hip area, especially with the new hip rule added to the 2016 edition of NFPA 13. Hopefully this will eventually get added to the attic head datasheet. I got suckered into using SDs on an offset and it was a nightmare. But yeah, HIPs are basically no good anymore. I haven't used any in about 12 years and for some reason I design a lot of attic systems...
