I use X-18 irons 4-9, and a 3i rescue club. I have tried BB irons in many guises. Personally, I’m not keen on the wide sole big bertha irons (3-5). Although I see the point in them, my fear is that there has to be a compromise somewhere…..like, how well do they work off anything less than a good lie? Is there a difference/advantage for a player who sweeps the ball as opposed to striking down? Much to ponder. The pull bad shot is unlikely to change one way or the other with either design of club – unless the BBs are MORE OFFSET than the X-20s in which case, I’d avoid. If I was buying tomorrow I’d probably go for the X-20s 5-PW and two rescue/hybrid clubs. If, however you can hit a few (test them out) with the 3-5 wide sole and they work for you, then you’ll be truly confused.
