Agreed with you here, OP. Magnum XL's ONLY, and they are still a bit too tight (but infinitely better, obviously, than other brands).
To me, they are a good, quality product, and not a bad price (since they are saving my life, in more ways than one.....).
Yes, I wished they made a more "custom" size, but the profit margins would be low enough they wouldn't make them for long, or in any quantity.
