it all depends upon how you wish to see your line grow.
if you wish to saturate a market, then the larger show would be good.
you're reaching a wider audience. but you could run the risk of getting lost in the shuffle.
if on the other hand you wish to start slowly and smaller and be noticed, then you can start with the regional shows and then expand.
it comes down to what product you are offering.
if the product is unique, at a good price point.
is your manufacturer able to deliver by an agreed date ( so important)
it all comes down to what you feel comfortable with.
Thanks for the feedback! Of course, I'd love to be able to saturate the market but I definately do not want to get lost in the shuffle. It's such a tough call and lot of money to risk but I totally believe in my products.
