Nevertheless between jobs i always clear the bits with acetone and then oil the for conservation. Using a soft piece of towel and carefull not to cut my fingers. The big benefit of straight bits is that they are much cheaper to run, cause they could be sharpened very cheaply and even by you, just passing behind the edge with diamond file. So a micrograin carbide 2 or even better 3 flutes straight bit will always be my preferred bit for wood, laminate, and similar.
