I'm with Joe on this one. My most used size is a #3, and my go-to blade is the FD Penguin Silver Reverse. My last couple blade orders have just been 3 gross of those at a time. They cut smooth, are very controllable, and stay cool and don't burn the wood even on really tight turns. I normally stack cut 3/4" of whatever I am cutting, so they may dull a little quicker, but I love the way they cut. I use some of the others at times, like the Pegas MGT or the FD UR, but when I need good control for fretwork, I always go with the Penguins.
