That's cool...great story too, way to change it up and get followers to bite.I don't know the formula for weight but sounds big.
I mean no offense by this but who goes fishing now a days, especially for big fish, without a scale? I would be kickin' myself in the Aye if I caught a teener and did'nt have a scale or camera! I know everyone forgets things as they go out fishing, I've even completely forgot my reels one time, DOH!
