Either full or semi chisel chains, depended on the job.
On a 261.
I don't know how many chains, I can't keep track of that stuff. The rails were super soft and the noses let go with any substantial use. I think it's like a lot of things these days, the price is going up and the quality is going down.
I agree the new stihl bars look like a snow cone at a pride parade, but they are a better quality compared to the versacuts.
As far as the forester goes I couldn't tell you, I never used one for any measurable amount of time.
