detune or not detune that is the question

I have a guitar that i just don't play anymore. (I hear all the groaning out there.)  fact is i have three others that fit me better.  there seems to be two schools of thought on long term storage. one is keep tension on the strings so the truss rod doesn't warp the neck. hmmm.  makes sense.  two is detune to take stress off the bridge and body. that way you won't... you got it, warp the neck. they both make sense although the second idea is more logical. i don't want to damage it as someday my grandson might pick it up. both sides insist they're right. i'm sooo confused!  and by the way, i'm still in love with my epiphone dove. sounding better everyday.
