I never have blisters, just a small callus on the third joint of my right index finger.
If I go to the range and hit too many balls, I may produce a blister on the third joint of my right middle finger
For the last year I decided to leave my driver at home and only use my 3 wood off the tee. My rationale was a bit less distance but a lot more control.
I lost about 15 yards but gained only SLIGHTLY more control. The cost benefit analysis did not turn out as I expected.
I will be going back to using my driver on most holes and 3 wood only on very risky holes (especially narrow fairways).
My own experience. With irons it's not so critical to try to hit from the inside. It happens by itself almost automatically because irons have a more vertical angle of attack.
With woods and driver, given a more horizontal angle of attack, if you don't make an effort to hit from the inside it's very easy to come out of plane and hit bad shots.
Hands too low, stance too open, knees flexed too much, etc.
I'm no expert but I have read that most people fall between two degrees upright to two degrees flat AT MOST. Very few people need three degrees upright or three degrees flat.
