M1 exhaust T is nice. I have them on my travel rig, which is Ti2/B2 combo. But in reality, I don’t see much difference between M1 T vs B2 T. Both do the job. No bubble in face.Don't forget, the M1 also comes with the wider exhaust tee and an extra heat sink that is supposed to make them better in cold water.
The Z2 is great for single tank because it does have a LP port on the bottom, and it's pretty darn inexpensive. For any reg that might be used in something other than single tank, I would just buy M1s. I bought my Z2 set after I already had regs for doubles and knew that my Z2 set would be strictly dedicated to only single tank.
The heat sink, I also have it on all my B2 2nd. To me, it is more of a cool look. Not sure if it does anything. The only reason I have them is because I bought them for $5 each here many years ago. I bought 3.
I do feel the M1 face plate is a real but maybe small benefit when swimming against current. My B2 is tuned so hit it will flow with moderate current or when I am on DPV.
If I am starting new today, and don’t have the resource to buy used, I will buy z2 and call it good tho.
