I've heard the inside diameter varies by brand. The difference is whether the brand quotes its pole's diameter based on the inside or the outside diameter (pipe or tube), and my club knows from experience that Innova poles and DGA poles are different. Ultimately it may not matter much, as long as you don't mix and match baskets and poles between brands.
