The Ping i15 is a great choice for mid-handicappers trying to get down to single figures.

Our mid-handicap testers achieved great results with the Ping i15 irons.
They liked the compact head, the semi-slim top-line, and the sheer quality of the club.

Results were impressive, a fairly high launch angle with a nice penetrating flight. Not the easiest club to shape, but very
accurate in a straight line. Feel is solid rather than soft, but a lot better than earlier Ping Irons. Powerful golfers with very
fast swings may find the launch angle a little too high, and would probably prefer the
Ping S56.
Our verdict
A great golf club that will especially improve the game of mid handicappers.
