I will go try it again, just to make sure. I don't want to sound like an idiot (too late)
Here is my little set up: lews speed spool ss1s hla , line: 20 lb spiderwire stealth braid , rod : daiwa aird 661 mxb. 1/2 oz lead sinker. I don't have one of those fancy rubber casting thingys.
There is a slight cross wind here, just now casting across the wind 1st cast set tight 27 yrs. jacked with it a little, second cast 42 yrs no backlash, 45 yrs for the 3rd with a slight cross wind. tried one more really chucked it this time, broke my line, so I must have had a back lash that I reeled over. Anyway I am still practicing, I know that I am green at this.
I guess I was just trying to set this thing up and find the limit, it sounds like mid to low 40s is it.
