FAT!!!! I go for a fat, wide, tape. 3/4" minimum, maybe 1". 25' seems most useful for me. I like the Stanly as well as Lufkin, Kobalt is fine too.
One trick - If you are working with more than one tape or have a helper with their own tape, make sure they are 'calibrated' to each other. The ends can get worn differently or bent a little. Just make sure they both read the same. You dont want to measure 31 1/4" and your helper hands you 31 1/8"
