I had 3 sets earlier this year, but once the Cobras turned up I flogged the lot. It's hard to commit to a set if they are constantly under threat from a previous favourite. I do miss the MP32's though. Might have to keep an eye on eBay after Christmas..
Got some old Titleist DCI 962 irons last week for pennies, mainly to clog about with in the winter for a laugh.
Usually use Cobra S3 Max irons which are ok but look odd at address given they're chunky as buggery.
