I bought an Atomic Aquatic M1 and I have it Purely dedicated to my Nitrox but does it make for a good technical diving regulator as well as trimix gas too

Absolutely. One of the best regulators available for technical diving.
Actually, as fine of reg that it is, I did discover a design flaw if used for deco bottles in cold water.
Because of the reverse poppet, when the reg is off, water can flow back into the first stage. Even though you should charge your reg before you descend, it's possible for the pressure to be released from the second stage, and then water can flow into the first stage. Then, when you turn on the reg and begin to breath from it, the water in the first stage can freeze and cause a free flow. Or in my case, sputtering, and complete reg failure.
I experienced this several times. I didn't know what the problem was, so I had it rebuilt. The problem happened again, so the dealer replaced it with a new one. It happened again, and I called Atomic, and they confirmed that this could happen due to the reverse poppet. They suggested to charge the reg now and then during the dive, if used on a deco bottle. I do this, and turn down the 2nd stage and I haven't had the issue since - but what a pain. If anyone wants to trade my M1 for a MK17 or an XTX50, let me know!

I always wondered about that. It also made me wonder about gear washing too.
Yeah, the manual tells you to have the reg on a tank pressurized when cleaning.
