Both Matt/MCW and Rooshooter have a ton more experience with different chains than I do, and they are adamant that their Carlton Semi held up better than the Stihl chain, and we get the Swiss made stuff here.
I'd like to say I've got a reasonable amount of experience Rick, but Laurie (rooshooter) and Bob (BobL) would pump me in total. Bob has some interesting hardness tests on chain that I think he may have done himself? If you do a search on this site you should find it.
One thing I have done is compare chains together on the same wood (and even on the same loop) and I can honestly say in semi chisel Stihl has been far from impressive. When you pay around USD$120 more for a 100' roll in Australia its bye bye for Stihl as far as I'm concerned.
I know in 3/8"LP Carlton is the preferred chain for Almond pruning contractors that I've spoken to (very dusty, dirty wood).
Full time firewood cutters and guys with mills that I know also prefer Carlton/Windsor.
In saying that though, a local tree guy (not sure if qualified Arborist but doubt it) said he didn't like Carlton. But then again he only buys one 100' roll of chain every few years so hardly what I'd class as hard core - I'd go through way more than that in one year myself.
I plan to contact quite a big local arborist business and see if I can supply them chain etc. I'm interested to see what chain they prefer as these guys
are qualified arborists and on the saws full time.
Another full time firewood cutter said he wanted Stihl over Carlton because he's found Carlton too hard to file!
The main problem I have, and I'm not doubting that a LOT of people like/prefer Stihl chain, is whether or not these guys;
1) Do a lot of cutting? - be honest. Even I don't do what I would class as a "lot of cutting".
2) Have even bothered to directly compare chain brands?
3) Just like Stihl because everything they own is Stihl and most people on this site love Stihl.
4) Have ever even cut dirty hardwood?
5) Even know what really dirty, really hard wood is like?
I've cut green wood with all sorts of chain and they're all acceptable, however when you're cutting dirty old Aussie hardwood it then really becomes apparent which chains hold up better.
Please don't think I'm trying to start a Stihl argument or any argument, I'm not. Its just that whenever there is a chain discussion 95% of guys say Stihl RS etc. is the best chain on earth which would tell me, by using Full Chisel, that they really don't know what tough conditions on chain are like.
Matt.
