I can see this happening easily. Shops have a tendency to push a certain brand, consequently they tend to sell more of that brand. In addition, too many bow lines, cause sales to be spread out to the point where meeting minimums is more difficult. Quantity discounts can only be taken advantage of, if you sell more of a particular brand. A dealer will commonly drop a bow line for one of these reasons, none of them having to do with the quality of the bow. Nobody wants inventory to sit around too long and every shop wants to take advantage of quantity discounts.
