in our horribly hard and dusty grey box and iron bark,i find the 461 bogging down a little when falling,particularly when making top cuts in the scarf.
Even with a brand new chain,its not as reliable in the cut as the 064,which is why i carry the 064 with me.
Bucking is fine,but when ripping down across fibres,as in making that top cut,i miss the torque of the larger saw.
Having said that,the 461 has had about 3 hrs run time in total,so im hoping it will wake up a bit,and once it settles in i will get a DP muffler on to it.
