How are the new "U" grooves on the golf irons feel?

Not much difference, but we all know you cant buy a swing.

No diffence in "feel" ....THat will come from your swing and the quality of wedges you play.

The U grooves won't produce the same amount of spin as the V's...so the days of spinning a ball from the deep rough or bunkers and whatnot will be few and far between....I don't think this ruling effects Amatuer players for several years to come...By then you will need new wedges anyway.

I was once told by a Pro playing on the Asian Tour that he will only play a wedge for about 100-125 hits then it gets replaced.........

Apparently the Y-grooves wedges produce more spin and less ball tear than the U and box grooves

The grooves do not make for a different feel, they just impart more spin since there are more distinct edges to the " U " than to the "V" configuration.

The feel will be the same. The ball will spin a little less, especially from the rough.
