I agree, the BA is really not needed. I have both my tanks set up on herbie (including one with a HOB) and have never had issues. My 210 is 1.5 but I don't see an advantage to 1.5 on a 70. 
 
I use acrylic baffles in a glass aquarium. They work fine, I just have them stuffed in between a big bead of silicone. I even built a flat top piece for a sock out of acrylic and it works fine as well 
 
Also where did you hear mags were quiet....
