Most of my chain issues have been with cursed Vine Maple the jerkyesd junk i have ever cut it realy hate skip tooth chains.I have found [in my experience] that stihls skip more then husky. I figured this to be due to the smaller chain guide diameter. I also should point out that this is an experience i have had well falling not bucking. I ran 288's with 28 and 066's with 28 as my bread and butter for years. Having said that i like a bit of droop in my chain; just at the point where the chain starts to hang out mid 28 inch bar. I figure i have less chain resistance and more power.
An example of my experiences is I found just the act of larger humbolt pie chunks from 3' dbh trees dropping out could knock my chain off a stihl but I never had that happen with a husky bar & chain. Not really a big deal as it only takes a few seconds to snap the chain back on with a quick bar bend.
If you have never skipped your chain much then your likely lucky to have not spent much time cutting slash alder and other underbrush. [most folks i know generally refer to this as F*k brush becouse thats all one is likely to say well working in it] Does not matter how tight your chain is for that wippy crap
