Im looking on the net and I saw a Taylormade r5 non-conforming driver. Is this driver worth it, i mean what more does it have, or do than a USGA r5?? Is it more worth it to get a non-conforming driver for the same price as a USGA r5??? .86 vs.83. How much better is it? Im not a tourny player so im not really worried about how illegal it is.
