I'd like the manufacturer to explain the "vertical velocity enhanced
pitch" in the Tru-Trak ADI. I'd hate to rely on that in IMC in wave
conditions if it is doing what I think it is.

There are smaller mechanical AIs avialable at least in panel space, may
still be too much for you behind the panel, and they will cost you
more (in cash and power consumption). For example the Mid Continent
4200 series, if I wanted a real AI that is personally what I'd use.

There are several interesting small EFIS systems available for
experimental aircraft, but thats a lot more integration that just
plugging in a AI. For example look at Dynon EFIS-10.

Many people seem to be going with the Tru-Trak pictorial T&B (no
pitch).

Dear Sir,

I read carefully the various posts on this newsgroup about the subject
(egyro-solid state gyro etc...).

In order to avoid heavy cabling, and minimising the available space (on
the instrument panel) and volume (behind the instrument panel), I am
slowly coming to 2 options:

Option 1 : E-gyro 2 (the instrument with a 57 mm in diameter) available
from PCFlightSystem.com. Only 2 axis available.

Option 2 : ADI from Tru-Trak which seems to be more complete i.e. 3
axis system.

Does anyone have a pragmatic experience on those systems?

Personaly I am not interested by a PDA solution because I need the PDA
for the moving map aspect.

Many thanks,
Bruno
