I'm 22.7, cut twice since January and I think the trend is going to continue. I've played for 2yrs 8 mths, last year I took lessons regularly, practised and played once a week. My swing looks better than my handicap.
I use a ProV1 in the summer and NXT/solo in the winter, mostly on faith that the lower compression helps in the cold, but I can't say I notice the difference. I'm better at putting with a ProV1 and we have extraordinarily fast greens so I need anything that can stop on the green.
Regarding the price of equipment, you're plain daft if you think gear will buy you less strokes.
