Make your product with the best material possible.But make it affordable and easily accessable for the average working fisherman.
Remember that word of mouth is your best sales tool. Get your product out in the rivers dont worry about the cash right away becouse it will come in due time. Fishermen are a very loyal group and if they like a product they will always use it. And we love to tell others about our success even more when using a new product. Cutomer service is the rule keep them happy no mater what the price.I would not worry about the packaging,infact the less packaging the less litter for the river.You could stress envirmental friendliness as a sales tool. I bet the Canucks would like to try some of your product the have alot of bait restrictions on thier rivers.
Good Luck.
