James,
I concur with your choices on the keepers and even more on the ones to cull out. It is an impressive collection but even a few of the ones you once loved should go. I have down sized to 7 keepers and even one or two of those will need to leave sometime in the future. I foresee that I will need to send some very great and loved bikes away as I age out of the cycling activity. Good luck in the endeavor. Smiles, MH
