From there:
Full-Skip is our best selling sequence. It is usually preferred by customers who run long bars and cut large softwood trees. Long cuts, common in these conditions, require the chain to carry chips a long distance before they are expelled. Since chips ride in the spaces under and between the cutter teeth, users have found that by reducing the number of teeth, a chain's chip clearing ability improves. On long and deep cuts, this enhances its performance. A side benefit is that it takes less time to sharpen than the other sequences. Its bad traits include that it is prone to vibration, its lack of cutter teeth make it grabby in short cuts, and its kickback potential is high.
Bars 24" & Under
When running a bar length of 24" or less, full compliment is the best choice. It will always be the fastest and smoothest cutting sequence on short cutting attachments. Even those who are tempted to select a skip tooth configuration to reduce sharpening time, will find full compliment doesn't take much longer to sharpen. On short bar applications, there are are not that many more teeth.
