Rubber was RZN is......

Crap according to my playing partner who said they felt like hitting a brick off the driver face.

anyone else used these yet??

strange feel, strange noise off the driver. Maybe I'll wait till the summer before chucking them in the practice bag. Ok off the irons, wedges and putter but not a match for the mighty V1x.

was considering asking the missus to get some as an anniversay present... but maybe not now.

Used the ball last year, and quite like them.  Can scuff up a bit quicker than other balls though. Settled for using Z-Stars as my ball of choice!

Interesting piece of marketing b*ll*cks too.  No modern golf balls use a true rubber core any more than modern car tyres are.  It's true that they may use a small proportion of natural rubber (a car tyre uses between 20% - 45% natural rubber) but they are mostly made of iomer or elastomer resins.  The point is, because of it's astonishing properties, natural rubber is an ideal addition to synthetic rubbers because of it's almost limitless ability to be compressed and store energy, something that a purely synthetic substitute cannot acheive.  If you don't believe me, try hitting an old Whammo superball with a golf club - my brother once demonstrated this by smacking one over 300 yards out of the driving range - with a 7 iron!
