I think the most important aspect of cutting with a 2/0 blade is tension. The blade needs to be tight, tight, tight. Most blades will not break at the proper tension. When you pluck the blade, it should have a high “ plink” or “ping” sound. The higher, the better.
For me, the only 2/0 blades that track on the line properly are Olson reverse and skip tooth blades. All other 2/0 blades including Flying Dutchman an Pegas just don’t track well.
