I prefer block cheese off the delly everytime.
I used to work on a delly counter and remember this fussy old woman coming in every other day for her 4 oz of mild cheddar, if it was under she would moan, if it was over she'd moan, one day I got it exactly right her mouth was working like a fish out of water, but nothing came out.
Needless to say I never managed to get it so exactly right again ::)
