Thanks Jet. I do not plan on buying another bike for a while (we know how that usuallyworks out). The LBS owner said that with either bike he didn't think I'd need to upgrade anything, but perhaps the biggest bang for the buck would be to get new wheels (not sure what difference a wheel can make). He seemed to indicate that wheels are the areas where I could shed weight and would actually feel a difference. Both come with 105 components, but the Elite has a little better outfit, not sure exactly yet. Can't wait to get back there to try them out again.
