Not a bad idea, but I'm betting more than 50% of the people wanting shoreline haven't even had shoreline.
There will always be greener grass on the other side of the fence, and always a new strain on the horizon. Getting a great cut is sweet, discovering a great cut is even sweeter.
I'm also kind of an old dude so i've seen favorites go. Bye bye lumbo gold, maui wowie and thai stick, hello shoreline, bubba and lemon larry. by all means hold what you like, I'f you get the devil's harvest beans and the cut you should be set. Cross a few males from the beans to the cut and you would likely have a great back up of approximations for your whole life.
