Well, these guys make them to 56", so that's 8 inches difference on the club - 16 on a 2 club drop.

And what is worth noticing is, that this is not just a matter of distance in one direction, but a matter of AREA where dropping is legal.

Some quick maths says that the drop zone using a 48" driver is appx 7200 sq.in. - but with a 56" chest-putter, it's appx 9800 sq. in.

That's an increase of appx 35% over the driver.

"Pretty minor"? I don't think so.
