My ms 460 pulls square chisel skip around a 60" bar (see avatar). I have carlton rip comp chain (reel) that I was disatified with so the oregon skip. More thought would have taken me to grinding every third cutter off the rip chain after making loop. If that doesn't work, when I make a 42" loop, to my satisfaction I'll try 2 on 2 off. The skip chain is hard to tell from the rip since the square is close to 10* as delivered, and correct feed rate for situation is more important to surface than which chain.
