for those having issues with wearbars bending, it really depends on the type of soles you have. The softer the sole, the more the screws will bend - and by "bending" I think you mean "folding" under body weight? as these screws are pretty tough to "bend". Also, the more screws per sole, the better weight distribution you'll have on each screw. I know some that use 40+ lugs per sole and have little issue.
Simms boots with vibram soles work very well with wearbars. I've also had good experiences using wearbars with korker boots as these soles have that hard orange plastic throughout it's length.
