Cat Desert Gold (now Cat Extreme Application- Desert) for years. I tear them down every season and they seem to always look great. Less than $5/tube, slightly over 1 tube per side.
Oh yes, thanks for reminding me about my favorite thread once again. I will be switching to a mixture of Vaseline and KY Jelly for the back half of the season. Will post results after prerunning the Glamis 1000
