Callaway X16 irons

Hi All,

First time post.  Great site, looking to use it a lot more

Looking to get a new set of irons.  Have a cheap starter set I got about 5 years ago but now really want to lower my handicap!!  Local golf shop have a second hand set of Callaway x16 irons 3-pw for £220.  Is this a good buy??  Seem to be in good nick and I can bring them back within a month and change them if i'm not happy with them, so i've nothing really to loose.

Any advice?

Thanks

Adrian
