I bought a bead rider cushion last year before a 7800 mile ride and I have come to really like it. According to the company literature the bead rider not only allows air flow around your butt but also distributes your weight better and reduces pressure points significantly. I never had any problem putting on the miles with the stock seat but the bead rider does make things more comfortable. I have no idea why it works but it does for me.
Good luck
