I do not know of one who does it. But lets be clear, TDI is one of the tech agencies and their standards allow it.
I'm not totally sure about that, part of DP standards involves valve drills. That's not single tank.

The issue is that you have a biased opinion about PADI's TecRec program, and you're not prepared to change your opinion.Other then single tank, I don't like using regular nitrox blends for deco but that is not as big a deal as it just means a bigger tank.
I've heard they now allow the use of trimix for below 100 to taught in conjuction, which was my other complaint.
This illustrates how you draw incorrect conclusions from things you didn't read but made up yourself, followed by forming a biased negative opinion which supports your already negative attitude.So your claiming that tec 40 does not teach using single tank for deco dives. When above was stated it still does.
That is considered unsafe in the tech world as you cannot do proper gas planing doing deco on a single tank back gas.
This is next to several requirements for all gas volumes.The open circuit equipment configuration employs a double cylinder configuration (sidemount or back mount) with all required equipment in a streamlined configuration based on a philosophy that minimizes confusion and procedural error. The standard technical rig provides back up of essential components, but eliminates the unnecessary. This equipment configuration is optional at Tec 40, but required at the Tec 45 level and beyond.
Tec 40 divers can dive in a single cylinder configuration, because the depth and decompression time limits are very restricted compared to broader technical deep diving. Even so, you will need at least one additional cylinder, plus other equipment you may not use often or at all when recreational diving. The same philosophy of using a streamlined standardized technical equipment rig applies to configure your equipment for maximum efficiency.
Exceeding Tec 40 limits (40 metres/130 feet and up to 15 minutes total required decompression) is not acceptable or reasonable with a single cylinder set up.
A single tank with an H-valve has 2 valves.That's not single tank.
Make sure you let TDI know, then. Last I checked, single-tank (H-valve) was within standards for DP.

Valve drill still applies to a single tank with H valve.I'm not totally sure about that, part of DP standards involves valve drills. That's not single tank.
