No I didn't do it own my own.
When I first started I got 3 private lessons for 2h each with basic lessons in irons, chipping and putting.
During the first winter I also had a couple of extra lessons with irons/driver/fairway woods.
When spring came around I got a couple of lessons with chipping and putting.
So I had a lot of lessons in the beginning but since then I also practice every change I got during 2020.
On average 2 times a week with 1-1,5 hours on the driving range and 1 round on our 6 hole par 3 course.
Practicing "real" golf on that par 3 course has helped me the most I think.
Ideally you would want something with more weight change ability. Even pulling the 3.5 all together isn't going to get you much change in SW. I ended up dropping about 8g to get where it felt right in my Epic Flash I used. But if it's all you've got and don't want to spend more on an experiment, then give it a go. I would suggest that you find a shaft as counterbalanced as possible in that case to try and even out the weight.
