Saw a picture of a Ryoma Beyond Power driver face. There are no groves in it. What gives? First time I've seen a driver face that is 100% smooth?

Thats funny, the beyond power driver is the same Maxima head for the past few years and only shaft is the difference. Both my two Maxima have 'groves'. Perhaps you should attach the picture you have seen.

Follow this link to one on sale at japan auction. look at the face picture...no groves

Looks like real maxima

The driver face has been shaved and I believe the seller stated that it is now non conforming.

Face shaving like that is risky business, also for the price that driver is in horrible condition, better deals in the b/s/t.

It's non-conforming before it was shaved

Thank you Chris, I thought this was peculiar. would think that face shaving is really risky on this driver head, given that it is a special tuning model

I didn't find a Ryoma Beyond Power on BST...??

Strange....there was one for sale with a Maxima ST head but it seems to have been removed. Perhaps sold already.

Place a WTB ad I know someone had one recently.

Great shaft & Driver but yes your right special tune + face shave = breakage.

Special Tune is already not suited for 100mph+ speeds.

Not sure why companies our scoring lines on drivers other than people are used to seeing them...they serve no purpose...

I believe they impact spin rates and wet club faces, I'm told it depends on the head design as to what the groves do or don't do in relation to performance. Anyone know for sure?

SMT, a US component company, made a few driver heads with no grooves about 5 to 10 years ago. SMT O2, SMT 455, SMT Encore...

Same for Krank heads, no grooves. Actually, I think I read somewhere that many "grooves" aren't really grooves ie actual dents in the metal but rather just burnt in score lines.
