When I changed my irons at the back end of last year I really considered the jpx irons. I really liked them and had similar results with the pings it just came to a personal preference thing really. Nevada bobs let me take about 6 demo irons from different brands all up to the range so I could try them in my own time-if you can do this I'd recommend it. Then I went to a different shop to get a better fitting
Just an FYI, the burner 2.0 are end of life, don't be fooled by the American golf offering the "new" chrome versions, it's an old club, replaced by the rbz iron. Don't get me wrong, they are cracking clubs, I use them and really rate them! Just don't want you buying what you think is the latest and greatest, only to find out they are end of life.. Not that it really matters....
