I partialy agree with you...but to be fair we must also consider that 95% of the stuff made to day is a copy of something that was designed at least 10 years ago. Especialy in the tent sector of the industry.
Check out that cam hook that is designed specificaly for pin scars. It has a bend in it that seats perfectly in 1/2-1 inch Angle scars, way more solid than the leeper design. The mallard is kind of like a beak, but seats nicely in the tiny crevases that you find in the bottom of pin scars, you know...the ones that won't quite hold a small HB off because they slope downward too much.
Ifound both peices at Marmot in Bellvue last year.
