low-kickback chains

i've h'eared that Stihl requires saws be sold with low kickback to limit liability. They cut slower. The speed loss is just not in pro-duction, but also reduces the speed-force of how hard you can plot to throw something around or away from you. Just like you can do more tricks with an 020/200 than an Echo whatever; the quicker/cleaner release can give more force to the throw IMLHO.

Safetys are for sticking out of the cutter line as the chain curves around the highest kickback position of the nose curve; making it harder to grab wood and kickback. But, as noted; this limits boring in with the nose bearings, for other 'pro-level tricks' and a different type of safety strategy sometimes.
 
when this stuff came about in england some time ago, we started to experience crankshafts shearing, not just on the older saws we ran it with, but we got a batch of 10 new ms200 and 1 crank sheared.
i have been out of touch with the uk for some years so im not sure if this was a major problem, but certanly at our workplace no one had seen this before.
the blame was put on excess friction from the chain causing a shearing moment on the weakened crank.
anyone else had this problem?
i havent ran this chain since and i hope i never have to either, as tree spyder says it just will not give a clean fast cut.
 
I hate low kick-back chains too.

I gave up on low-kick back chain the day i bought my chainsaw. I went to STIHL RAPID Super L Full Skip Klassic it uses a triangle file at first can be a little harder to get use of sharping but once mastered the chain stays sharper longer and cuts faster than round chained
 
I gave up on the low-kick back chain to it just dose not clean the cut out like a regular chain and now when you buy a new saw it comes with a low-kick back chain so I tell the saw shop to keep it and give me a regular chain in place of it my saw shop will do it if they can.
