Around here, the bigger shows are the more expensive shows. I don't consider many small shows unless it's for charity, etc. I would say to give big shows a shot. You never know until you give it a try and every business has risk. I don't think investing tons of time and money in to shows are worth 60-80 profit so I would definitely try something BIGGER.
To find the good shows ask other crafters (not bow makers) what shows they like and do well at.
