You can buy any Japanese clove oil, that's what sword oil is, not sure if the Gold's Sword oil was in the pro shop last time I looked, if it is grab it from T.... It really does smell great, it's basically mineral oil with a tiny bit of clove in it for the scent, it won't take the bite off your raw heads at all, I believe Yururi ships there clubs oiled or at least the last few wedges I have received from them have come oiled, it bonds to the metal to keep from oxidation(rusting), and it's DEF a good idea if you want your raw heads to look pretty and new for a while... Although if your just looking for max bite, allowing for a bit of rust on the face will give you that....
Yup, ive got the flatbacks, I have them in satin though, they're DEF one of my favorite blades, AWESOME to shoot at pins with, in my opinion the best scoring irons in golf, and this set is my go to links iron set without a doubt, very razor blade like clubs and they're pretty strong lofted for blades which brings the flight down a touch more, these really eat links courses alive when you really need precision iron play.... A pretty demanding club, you won't find much else out there that gives you more of a challenge, but they are very, very sweet when struck pure, very workable, no problem moving these any way you like.... You got yourself a fantastic set of blades there that excels in the hands of a skilled golfer mate.... Also your shaft selection for these is pretty much top notch for this set that's available retail, ive tried alot of shafts in these and have continuously came back to the Modus, i originally tried the Modus in them in Stiff which were a bit soft and thin for me, but once I found the correct flex in the Modus they went better than anything else I tried in them.... SP Blues in them were a bit low and the ball didn't wanna move at all, Monacos were good but again I really wanna move the ball with these heads and the Monacos are pretty much dead straight, Crazy Steel 120 is a very solid option and so far would def be my second choice to the Modus but the Modus get the nod over them in these heads for ease of use... Only other shaft I'm waiting to try in these heads is the NS Prototype C10, I have high hopes for these, but if I still prefer the Modus in these heads then I'm gonna keep the Flatback/Modus3 setup and give myself a pat on the back for getting it right the first time, lol...
