1) Allbino's gives overall transmission figures. Here is the link for the Zeiss 10x42 FL which is 95.5%.

2)The total transmission of the 10x42 EDG is 2 to 6% lower than the SV and HT. Zeiss lists the HT at 95% transmission. Here is a link just click on the reviews for total transmission on the 10x42 EDG and 10x42 SV.

I did some research on your Zeiss 7x42 FL and I found a transmission figure of 93%. So it is very good just like the 10x42FL. All those big Zeiss FL's have AK prisms just like the HT which keeps the transmission high.The big Zeiss with the AK prisms are the top transmitting roofs on the market. The only thing that will beat them is a good porro like the Habicht 8x30 W(95% transmission) or Fujinon 7x50 FXT(97% transmission).

So...a question for you...

Had you rather have a somewhat bell-shaped curve at 95% or a flatter curve at 88%? It seems to me one would want the the flatter curve to give the best color representation?
 
Seems like I've heard those descriptions before. :-O

Yes!

If only the Habichts were comfortable to use; had well designed comfortable eye cups; reasonable eye relief longer than 12mm, 13mm & 14mm; focusers easy to turn and modern FOVs of at least 7º on the 40mm versions everybody would have one!

The Habicht's do have their quirks but when it comes to optics they are some of the best binoculars you are ever going to look through. Kind of like a Lotus Elise. Not very comfortable for a long distance trip but sure nice on a curvy mountain road.
