Beyond the introduction of the spider line it is unnecessary to mention the various steps by which the Gascoigne micrometer assumed the modern forms now in use, or to describe in detail the suggestions of Hooke, 4 Wren, Smeaton, Cassini, Bradley, Maskelyne, Herschel, Arago, Pearson, Bessel, Struve, Dawes, &c., or the successive productions of the great artists Ramsden, Troughton, Fraunhofer, Ertel, Simms, Cooke, Grubb, Clarke and Repsold.
It depends if you're going for a long shot with power or a short shot with power. I'm going to assume you're going for the long shots. Take about 5 steps back at a 7 o clock aâ¦ngle to the ball. Take 3 quick, tiny steps then take a really fast run up.
Typically a flat angle of attack or a bit of an upsweep is preferred for almost all golfers. Again, that high launch with low spin condition! Typically, given a ~90 mph swing speed, 13.5-14 degrees ball launch (not necessarily driver loft) at about 2900/3000 rpm is close to optimal. But as stated, it depends on the golfer (and the golf ball).
