You're welcome, again, no disrespect intended or implied. You didn't really state your experience level or run group but the way you asked about the upgrade makes one think you may be a little new to this. I know I asked atleast one or two of those types of questions when I was brand new to this. Books and video about this sport along with ride alongs will increase your speed more than you can possibly imagine. Anyway, best of luck and have fun.
