Well like the saying goes, A bad day fishing is better than a good day at work.
Don't beat yourself up to much about your blank. This time of year is not really langebaan weather. I bet not even the langebaan king, Scorpion, could have pulled out anything.
Just one note on the wind. We have caught some very nice bloukoppe on the strong NW in the baan already. So it's not impossible, by all accounts, strong SE is preferable - a few days before and on the day,.
Look on the bright side, you now have the real "skietgoed" for the steenbras. Some nice ones showing at strandfontein recently.
