Well, I've made my first cuts with the ATOP system after sharpening the semi-chisel .325 chain. And I'm loving it. My first impression was that it cuts like if the rakers have been filed too much - but without the grabby, bouncy feeling. The cut just went through the log - fast. The second thing I discovered was that much less pressure was needed to get the cut smooth and fast, the tooth seem to work its way into the wood more by itself than the standard chain - and with those plate angles I kind of suspected that... I tried some boring as well to see whether it would throw the saw in my face - but again, those "agressive" angles really cuts through the fibres making the boring cuts "boring" - I felt no tendency to kick back at all. Overall I'd say that what Goran promised - he delivered. I'm just curious why those of you who have "been there", "done that" abandoned this kind of filing if you've really succeded in filing with this kind of file that is.
If I find square filed 3/8 much faster than ATOP .325, I'll probably go for it. But I doubt it after todays testing. The wider kerf made by the 3/8 probably generate too much friction to be a winner for those small saws. Now, for the record, I just want to point out that I have NO connection to ATOP more than that I've just bought the file guide and talked to Goran on the phone. I'll continue my testing after easter and come back with photos of the ATOP system and what I've achieved with it.
