A good teacher-- like myself (he said immodestly)-- could have improved your game a lot... a slice is EASY to cure... I had a near 100 per cent success rate with pupils who came to me with that problem...
Of course, there was one, LITTLE problem-- the way you teach somebody how not to slice a ball is to teach him to hook it... and in a few weeks, that student is usually coming back to me for help with his wildly uncontrollable hook... sometimes, I felt like a drug dealer, teaching them how to beat their problem, knowing that in a week or two or three, he'd be coming back to me for help with his NEW problem... LOL...
I was always a better teacher of the game than a player, because I could never putt worth a crap... oh, I didn't have many 3 putts, I always had a pretty good feel for speed... but I could never read a green too well, so I never made many of the putts you see touring pros rolling in all the time... pisses me off when I see them drop a 15 footer like it's easy...
I once played a Robert Trent Jones course in Wheeling, West Virginia, that was at the time an LPGA tour stop (Speidel)... a mean monster of a course, and I hit 16 greens that day, from the championship tees... the two I missed, I was 3-5 feet off the green, in the fringe...
I shot 74... LOL... didn't make a fargin' thing all day...
