Im looking for a 2nd blade for my Dewalt 12" miter saw that I have been
using for 12 years. Thought Id get a blade to have while one is being
sharpened.

Seems like most blades now are the thin kerf. Any reason not to use those?
Current blade is .125 carbide. I wondering if the thin blades tend to
wander more. I dont care about saving material in the cut. Dewalt has a 2
blade pack that is good price but they are thin kerf. can you recommend a
good all purpose carbide tip blade?

thanks for any tip!
