This reminds me of some of my regular Canon and Nikon customers. Every year or two they upgraded to the new "bestest" and often accumulated several models not being able to let any of them go. Due to my incredibly tough moral standards ( as a dedicated minimalist) I have managed to let some shelters go and I am now down to just nine.
Thank you for mentioning the Sublite, that one is bothering me a bit. I really like the Contrail but the Sublite design is stronger and lighter....(can I do without the vestibule ?)
