I hate the driving range. Wish they sold little buckets at my closest range, 70 is way too many and I lose focus and start sucking. Hit 10 1/4 swings with my 56* then 5 1/4 swings with my 6i. All good. Next 20 balls just alternated between 6i and 4h, working on my face angle and curvature. Hitting it great, high and soaring. Then I starts getting sweaty, harder to grip club, harder to swing easy, harder to focus. Started hitting low burners and even slices. Dropped back down to partial swings with a wedge, ok but not great.
I think I get much more out of practicing with a net. This happened a few weeks ago at the range too, went out the next day and played fine so no worries, but I think from now on I'm only using ranges where I can get a small 25-35 ball bucket. 70 range balls is counterproductive for me. I never hit 70 balls in one session at home in a net. Short, focused practice does me much better than long, ball bashing sessions.
Shoulda just went to the course.
