Interesting thread since the OP doesnt ask anything or push for others to chime in.

But then here are all these responses. I really think thats mainly due to how much this saddle is enjoyed.
I have 3 old style C17s with the cotton tops that fade to an unmatchable tan, and 2 current C17s with the 'weatherproof' top. Only 1 has a cutout and while I like it, I really dont think about it any more or less than the non-cutout style.
