Hi,
Personally I think it is a good thing. Pro Players are getting stronger and more athletic and get themselves out of most things including serious rough. With the current grooves they know they are not going to punished for an errant shot.
I think the new grooves will mean more thought process off the tee to make sure they stay on the fairways.
Also maybe not so much target golf. Not that this is ultimately bad as it can be good to watch, however it would also be nice to see some serious shot making and manoeuvring of the ball as it may not just bite as soon as it hits the green.
However I must say as it did in the Pro Tennis when they lowered teh compression of the tennis ball, technology will improve making the rule non existent in the end.
Regards !!
