Purchased an ATX95 a couple months ago. Currently it's on a 18 yr-old Bogen 3130 head (= old version of Manfrotto 128RC) and Gitzo G1227 legs. Immediate predecessor was an ATS80HD 20x-60x.
It is noticeably bulkier and heavier than the ATS80. You may need to consider upgrading your head and/or legs. My current head/legs combo provide sufficient support, a fair breeze (20mph?) had little effect. However the head needs to be locked down to prevent vertical flop. Also, my 3130 is a little stiff and ratchety at times, I was looking to replace it even before getting the ATX 95. So I'm am upgrading to a Sirui VH-10. The new Manfrotto MHXPRO-2W was enticing due to the new duo-setting fluid set up and the fact that the scope's foot fits directly into the plate socket (like the 128RC). Unfortunately, it was a major disappointment. The scope/socket fit wasn't tight enough and there was some movement of the foot within the socket. Much worse is that Manfrotto badly screwed the design, it is inherently unbalanced with the plate socket sitting almost completely behind the tilt axis. Everything wants to fall backwards even at the higher fluid setting. I wouldn't be surprised if even a 60mm scope would need to be tilt locked to prevent backwards flop. Too bad, I had great hopes for this new compact head.
On the plus side regarding the weight. It wasn't noticeably heavier to carry (legs resting on my shoulder) than the ATS80.
So far I've only had a 4-5 chances to take the ATX95 out. They have all been under good lighting conditions. One with occasional dirty air.
The initial view at 30x is usually fantastic. I don't get the immediate urge to crank up the zoom like I did with the four previous 20x-60x scopes I've had. Of course you're already starting at 50% greater power, but even so the view seems so clear, bright and eyefilling.
Dialing in perfect focus at high powers takes a deft touch with maybe a 1/32"-1/16" movement of the focus wheel. The one outing with occasional dirty air was puzzling. It was mid-morning at a mudflat on a new dredged spoils basin for our water supply lake. Clear blue skies, sun at my back, little or no breeze. At times 70X was sharp as a tack at 100-200yds, other times even 50x was quite blurry. There did not seem to be any atmospheric changes to cause the blurring. Also it seemed like I was doing a lot of focusing, but there was quite a deep field to go through, with birds from 25yds to over 200 yards out.
I'm fairly certain the ATX95 will really shine under overcast skies and at dawn/dusk. It was a chance to use a friend's Kowa 883 at dusk last winter that opened my eyes to the new larger diameter scopes and ultimately led to purchase of the ATX95.
