Can I be greedy and say I want to make money by developing a skill? If there is one thing I've learned over the years it is that betting markets change year to year due to, for example, an increased participation of online punters and the increase of info available to punters. A strategy might work well for a few years and then falter as the area you punt on gets targeted by pros or the info you once had to dig for becomes readily available.
I guess that is my reasoning for formulating my own strategy so that if my profits start to sag then I can tweak my approach rather than buying a different package.
Thanks for all your input and I guess I'll be putting my two cents worth into the forum next year.
