Head Covers on Forged irons

I use the Castle bay clear ones, no bag chatter at all and clubs still look well with no dings. Make sure you give them a quick wipe if playing on a wet day though just to stop them sweating and any potential corrosion.
Everyone has one stigmatic bit of gear in their golf bag, I have iron covers, others have hybrids,chippers,gps,rubber pyramid tees (those horrible ones tied to gether with string...)
