I was impressed with the full skip chain 68JX. First time I have ever ran skip of any kind. My forearms are still hurting. It does pull hard. It also chucks rocks pretty good. It is a 60" bar. I ordered a 50" but could not get it till June. But the dealer did find a husky 60 inch bar. The 44 inch husky bar is also backordered. I now understand how this saw can break 3/8 chain. Power! I am very happy with the saw.
