Kpantherpro.......nice designs, not questioning your product but the customer feedback, a csm will not cut faster or better than a bsm, in any wood or conditions. A dull or improperly sharpened chain will result in likewise performance of a dull, mis-set millband, or improperly tensioned millband.
Thing that work vary from place to place, acme and all thread are a near no-go in the winter months here,pulleys and cables work as do open faced gears.
Operating cost is another factor, 28"bar and say 92DL, that chain cost me darn near the price of two millbands, fuel and bar oil use on say a 395 or 3120, at least half a litre per two cuts in average size wood of 16" diameter, my bsm, run all day on 5 litre and put out on a good day close to 1000bf and bar oil? whats that? a lil water and the odd cap of pinesol and away we go.
Factoring operating costs and usage changes alot of things.
I like my csm, and bsm, carridge style csm doens not compute unless one already has a saw to run on it, or needs a highly portable (ie air/water and swamp kind of partability) with a bsm. Production and economic wise the bsm is they way to go dependant upon ones conditions.
