I also go commando, once i tried it there was a huge difference. also quality of knicks also makes a difference. i have a pair of GOS women's specific knicks and also a pair of custom knicks that the LBS that i ride with got made. I can't believe the difference. The LBS knicks i don't have any discomfort after a 100km ride, but after about 40kms with the GOS once it starts to hurt. The less the seams between you, the knicks, and the saddle the better in my opinion.
