I've been using a C14 since the 70's and I was waaaaay stronger. Still, at 60, it IS harder, but it's never been a piece of cake. I'm 6'2 and been in good shape most of my life, but the creaks and groans are showing up for sure. I've been using using it on a G11 for years, and recently put it on a CGX cause it's easier to set up and such. I was pretty worried about it at first, but it's been really great. No issues at all with dampening compared to the G11.
One thing that IS a problem, is that you SHOULDN'T extend the legs. The clamps won't hold the legs without slipping, and you could easily dump your scope!! I spoke with Celestron tech support since it's supposed to work with the CGX, and the advanced Celestron guys even hemmed and hawed whether or not the clamps should work. I mentioned that there should AT LEAST be a warning in the manual if you are putting a 14 on it!
This means that you will be sitting LOW if you look overhead... I MEAN L O W. For me, its super low. I use the Starbound chair, so observing low is fine, but if you have bad knees, you're not getting back up and down easily.
I put the CGX tripod on concrete blocks to raise it up and that works great. Course there goes transportability out the window!!
I got a C11 GPS scope for a retirement present from my wife, and while I love it, I had NO IDEA HOW HEAVY it would be. It's easily worse than moving around the 14.
Finally, FULL DISCLOSURE... I've turned into a bit of a wimp... My wife now helps me move stuff around. She's really SUPER GREAT! Everything is much more portable now!
