a previous question prompted me to ask: are the grooves on the KE4 U30’s conforming to USGA requirements? I think they were manufactured in 2010, so they’re right at the brink. If not, they would still be good to 2024 as long as not used in competitive play, correct?
Also, what current model Maltby irons are most similar to the U30’s?
We did not submit the KE4 U30’s for testing, but they were conforming. They would still be good to 2024 as long as not used in USGA competitive play, or any tournaments that use the USGA guidelines for equipment in the event. The KE4 S are very similar to the original U30’s, but we did not submit those either, if that matters. The KE4 Tour+ are also similar (a little less offset and only one weight in each head) and were submitted and approved and can be used in competitive play.
