I,ve barely broken 90 myself for awhile because my arms were not working together. I can't afford lessons but I found a pro online that I've been working on his stuff this last week or two and he makes a lot of sense. I can't afford lessons right now so his online stuff fits my budget, free. I broke 85 today because I didn't lose it much right at all all day today and I hit it a lot harder. Hit a ball in the water long and left for the first time in ages. Check out this if you like, i know the price is right. video's and he writes some stuff.
