Mike since you are willing and able to. With so few folks into building chains now days to see what they can gain for race and work. Why not do them both? If you have the saw cc that can do both.
I will step aside and you can do the longer bar 404 28" 063 and the shorter 3/9 20" 050. Just keep them in separate list IMO.
Choose a gear for each and cc stock or woods ported saw have fun.
