A few of years back I was in Orlando and on the lookout for a new putter. There were a couple of large golf shops to look at. I picked up a two ball putter and couldn't miss on the practice green. The salesman was insisting that I should buy but it sniffed a bit, particularly when a ball I hit past the hole still went in! Closer inspection revealed the not so subtle gradient all round the hole! Needless to say I purchased my putter from another store - I still got a two ball though.
