My CPC11 fork assembly weighs 65 pounds and is about 31 inches tall. I’m only 5’6” and that makes it a pretty big package for me to lift and carry. That said, after I practiced lifting it onto the tripod and removing it a couple times, it’s not really that bad. The handles on the side and bottom make lifting and carrying it pretty easy once you get it off the floor.
The Cpc11 is rock solid, and very comfortable to use compared to my EQ mount with a refractor on it. Not that I don’t like the EQ mount, but a fork mounted sct IMO is just a pleasure to use. No matter what size you decide on, you will be very happy with a CPC.
For reference, here I am holding my CPC11.
I'm 5'6" as well, but only 140 lbs. The CPC11 fork assembly would be almost half my weight. I don't know if I'd want to hoist a 65 lb fork assembly onto a tripod.
