what about chain gauge

[norma]

Is there a diffrence, performance or longevity wise on the diffrence between 0.050",0.058", and 0.063" 3/8th's chain? Seems to me the thicker chains would be easierr on the clutch rims but little else.

Not really, it is a "non" issue. The manufacturers have the 3 different
gauges on the regular size chain, just to be a pain in the ace.

.050 is narrower therefor it takes a little less power to pull it and is slightly more prone to stretch out of pitch on larger saws.
