I'm a scratch golfer and have been playing golf right-handed for most of my life. Sometimes when my playing partner is left handed, and I feel like showing off or making a few bucks or free beer, I'll bet I can hit the ball closer to the pin on a par 3 off of a tee with his club. Laughing and talk about how bad my left hand swing probably is happens. Bet accepted. I tee the ball up as high as I can. To his amazement or horror after a few horrible left handed swings, I go to the other side of the ball and spin the club upside down (hosel up) in a right handed grip and rip it. I usually win the bet. I do the same thing with drivers off of tees and I usually crush the ball way past theirs (about 250 range), their shock sets in and it is great. Teeing it as high as possible lets the toe of the clubs to clear and doesn't damage the toe. Most of the time I just use their exact club because you can adjust loft by twisting the club in the setup, teeing it as high as possible, and hitting it like a hovering shot, hosel up.
This has me thinking about what is the ideal iron number to use if I bought a left handed club to actually use off of the ground, toe into the turf. The ratio of the offset to hosel position on a 5 iron seems to be ideal while gripped right handed hosel up from off of a tee, allowing the toe to clear. The 5 iron toe (club face height) is the iron that decreases in size the most for how big the 6 iron toe (club face height) is. What if I wanted to hit the ball like a normal on the ground shot. Would a left handed 6 or 8 iron be ideal because less offset and higher club face left handed meaning flipped hosel up and used right handed wider hitting area? Which left handed iron gripped right handed hosel up and hit right handed off of turf would be best? Any opinions, science, answers??
