I haven't posted in months but can't keep keep quiet about this topic.
Do not EVER buy or if you have bought Iron Silk run, don't walk, it to the nearest garbage can. It is the only line I've ever stripped off a reel just to be rid of it. I'm WAY too cheap to not use a line until the last possible moment......except Iron Silk.
Let the retailer, no matter how admirable, wallow miserably in the un-bought inventory and let them demand a rebate from Berkely themselves.
