I would do a mixture of what you can afford.
Although nice to compare youself against your own breed, it is also nice to see how you fair against other breeds. I much prefer doing open shows in the sence that it;s cheeper, more local and you meet alot of different people. Though going in AVNSC, and also when I was entering rare breeds with the aussie shepherds a couple fo years ago, you get to meet so many more people outside of your breed which personally I love, it's nice to have doggy friends outside your breed,
as you are never in direct competition for them it's normally nicer relationships!Of course you want to do champ shows aswell to compare against your own breed but would you rather travel 300miles to a champ show with breed classes or 30 miles to an open show with AVNSC classes. Presuming you have already qualified for crufts and are not botherd about chasing JW champ show points etc...
