My go-to blade for making big pieces of wood into little ones (pen, reel-seat, spindle blanks) is a 1/2" x 3 TPI.
A wider blade would work just as well, but not, IMHO any "better" so the question becomes why bother going bigger if it won't do better? From where I sit, a wider blade just means more blade tension, which means more load on my bearings, with no appreciable gain in sawing efficiency.
I wait until someone puts blades on sale and buy a whole whack of fine-tooth 1/8" (scrolling) blades, 3/8" x 6 (general purpose, and usually mounted on my saw), and 1/2" x 3 (blank ripping/crosscutting) blades.
Notes:
1) I have a 14" bandsaw; and
2) There are 2 rules of thumb for bandsaw blades:
a) wider is better (except for cutting curves, of course) so you should go as wide as your wheels/guides will allow; and
b) you should always have at least 3 teeth in the workpiece (I cut 1" blanks and so the most aggressive blade I go with is 3 TPI)
Thus endeth the Sermon From Ottawa
