OK,so I was at 00 for about a month now,& decided to increase my size.Just got done putting in my 7/16" tunnels,which had to have been the easiest stretch EVER,much to my pleasant surprise!

I actually had to wipe off some of the oil I used because it was too slippery.I'm thinking I may eventually go up again in a another month or two,but I'm a bit confused as to what's next.Some sites I see list 12mm & 1/2 as two separate sizes,but not always.So if I do go up in a month or two,should I specifically get ones that say 12mm,or 1/2,or are they considered the same since there's only about a 0.5-0.7 difference?
