I sure wish you would give me some advice on my GSP/CM Spitfire. I'm having a heck of a time with these retracts bending on landings.
I'm using the cheap Hobbico or Dave Brown style and it's not cutting it for an 11LB bird.
I heard of some guys putting a thicker wire on them. Not sure what size wire you have or if you have the ability to bend some thicker. It would be cheaper then buying new gear.
