I've done plenty of deck work with 1" rigid. Many high rise buildings in Manhattan NYC. If I had to choose between the two benders,I would definitly go with the hickey.In my opinion the hickey allows you to be alot more versatile with your bending. I'm around the same weight as you 155 lbs. 1" rigid is a little tough to bend but you can definitly do it. A 1 1/4" emt bender is a heck of alot harder in my opinion.If you lay the pipe on the floor & Place the back of rigid up against a wall
you can safely really get on the hickey with all your weight..that should make things a little easier for you... ToHo
