I weighed my old hardtop a few years back, it was 188 lbs and had sliding side windows. The solid glass model would be a few lbs lighter. I have removed my top by myself a few times...it's doable but no fun.
Once it's all unbolted i stand under the middle of the top and using my back i lift it slightly and creep it back a little at a time. Then, i grab an 8 foot 2x4 and put it across the bed at the rear so the 'pins' hold it from coming off the rear of the bed. I just lift one side of the top and get the 2x4 under it, then lift the other side and do the same. The 2x4 at the back keeps the top from sliding off the side of the truck, or into the box.
Once the 2x4 is in place i grab the rear of the top and start pulling it rearward, until there is only about 18" of top still on the truck...then i lower the back of the top onto the ground so it's standing on end. At that point you can walk the top away from the truck and up against a wall (what i usually do)
I'd have to say it's much better with at least one other person to help though. My second bit of advice is if it does begin to slide and fall...let it go. It's not worth wrecking your back. I've dropped mine several times and aside from a little scratched paint it was fine after.
FWIW I'm 5'10" and 150 lbs...
Since I did the full convertable thing recently i finally got motivated to put together a winch. pulley's etc etc in the carport.
