I ride on a womens Specialized with no cutouts but a narrow channel. Like everyone's said tho...its a very personal thing and it just depends on each person. At the time I bought it, I thought it was a mens saddle which is what I was really looking to buy. I stayed away from the cutouts - they looked scary to me!
I kept thinking - what if I fall thru it??
Anyway, good look on your search!
Life should NOT be a journey to the grave with the intention of arriving safely in an attractive and well preserved body, but rather to skid in sideways, champagne in one hand, strawberries in the other, body thoroughly used up, totally worn out and screaming: "Yeah Baby! What a Ride!"
