but I like the curve on the bottom, does it help in thin cuts, like roundin things? What i,m realy wonderin is what to do for my 3/8 LP 16 inch bars, the 346 is eating them alive,but I like the cheap chain and availability. I have to customize the bar any way, is there one that work,s better? or do I just need to grease the roller tip more often, high speed delema!!!
