Florin, I have AOE's 30x100 binoculars, and I have balanced them on my Velbon CX-540 once - from the comfort of my office and then to look horizontally into the distance. Never outside, or at night, or to any elevation. If you have your 25x100s, you'll know that these are big, heavy, bulky items and using them on any standard tripod is a challenge - 1) will it hold them up and steady?, and 2) can I get any decent elevation of the binoculars without getting tangled up in the tripod or pan-handle, as you suggest? That is one hefty tripod you are looking at, but without trying, you won't now how it performs.
Now I have seen a review of big binoculars which does talk about tripod mounting. I don't have the URL, but the article I have printed is "100mm Binoculars - What Can You See" by Ed Zarenski and it seems to have come from Cloudy Nights Telescope Reviews in 2004 - so I'm sure you can find it.
Ed talks of using the Bogen 3246 tripod with the heavy duty Bogen 501 head. I have a suspicion that "Bogen" is what we know as "Manfrotto".
He quotes the 3246/501 combination as being $350 (US dollars I expect - Eeeeek!)
I'm sure you'll benefit from a search of this site and other sites, eg Cloudy Nights binoculars forum:-

for information on mounting big binoculars.
Good luck!
