I get the gist of your post Mark and I don't think too many people will disagree with most of the points you've made, apart from the fact that you seem to be saying that it must be OVO and nothing else.
That's a bit like sticking your head in the sand like a Dodo, which co-incidentaly is also obselete.
We're living in an age now, where there are 10's of 1000's of Music Blogs around the world and most of those blogs (especially the collectors ones) have 100's and, in some cases, 1000's of tunes on. If you go digging around these blogs, there's loads of great tunes which I've only just discovered after 40 odd years of collecting.
In the past - from 1976 in fact, I used to get on a plane, go to the States and spend weeks/months digging around record shops getting covered in rat shit and cobwebs finding great tunes.
It was possible back then when there were still plenty of record shops and dealers.
But that was then and this is now.
These days, OVO has become a rich man's pursuit. I don't know many DJ's who find their own rarities. Usually they deal with established dealers and hand over shedloads of money don't they? So this whole OVO scenario has essentially become a money game rather than a passion game.
In an age where you can dig around the record collections of the world to your heart's content from the comfort of your sofa and when so much great unreleased stuff is finally appearing on CD for the first time, it seems just nuts to me to limit yourself to one format. What's the point unless it's really fear of the unknown?
In the same way as you wouldn't consider using a wind-up gramophone in this day and age, I don't know why you would limit yourself to playing just one format among many.
As I've said a zillion times before, it's all about taste in music, so why limit your choices unless it's for egotistical reasons?
