I capitulate, I am grasping at straws there and pulling crap outta my arse!! You guys are correct that the AH is of course a better instrument in IMC conditions in an IFR Aircraft and possibly in a VFR Aircraft assuming the Pilots do keep an eye on them on a day to day basis and recognise when they are not performing well enough to be relied upon. But honestly I'd still rather use the T+B to get myself into a nice rate one to get back to VMC rather than the AH and use the AH as a backup to check I'm not climbing or descending, I shouldn't advocate it's sole use in such a situation this would be ignoring a perfectly valid source of information as Square Bear pointed out.
I should point out that was my point Square Bear, if you only have 178 seconds to live then you don't want to be using anymore of that than you have to.
