I went to the Husky site and looked at their fit up chart which would give me a good starting point. That hadn't occurred to me earlier.
Its kinda tough when working off a roll to tell how many DL's you need especially on along bar. On the shorter bars I take an old chain broke apart to wrap around and figure it out. I'm somewhat of a newby to making my own chains but I know one DL off and either you can't get the chain on or it will be too long.
And also the more I make the better idea I will have of what DL count typically goes with what bar length. I already know 16" bars are either 60 or 59 but mostly 59.
