Well, I can't really decide on the frame!

I'm down to a Mach 429 or RIP 9. Mostly ride in south FL but have some trips planned for GA, TN and NC over the next couple years. I don't race anymore and have been away from the saddle for an extended time. Looking to get back to riding but I'm an old guy now so I have no aspirations of really tearing it up. These two frames are aimed at different targets but I think I would be happy on either. Looking to come in at around 27.5 to no more than 28.5 lbs. It'll be my only bike other than a grocery getter...err, beer getter really. Anyway, would like to hear from folks that own either of those and trail ride down here.
