with an underpowered saw or fat wood less tpi work better `cause the motor dosen`t strain as much.
for general purpose work 4tpi is what i use.
i can cut a 3/4" dowel out of a 1x using a 1/4"x4 blade.
for resawing straight lines more body behind the teeth helps.
remember.....bandsaw blades are a disposbale item, the tips of the teeth will dull sometimes after only a couple of boards, so buying expensive blades may or may not be worth your money?
bi-metal blades all seem to last about the same to me and i use a feeder so my tests have some validity.
carbide is worth the money for a production shop but is not for anybody who cuts wet wood or bark.
