I have used picco super a lot on a 201 and some on a 241. The RS pro .325 chain I dont know what I am doing wrong, cant get it as Sharp as the picco super so now I am back with picco super on my 261. I will post some pictures later. The chain I have most sucses with is the C85 on my 560xp, but the problem is the RS pro chain, got it right the first filings but not anymore. The picco super and the C85 will cut god untill its worn out, but I noticed from when the RS pro was Sharp,that it outperforms the picco super.
