When I need to shrink around a stepdown, I use a butane torch for a final cinching. I use contact or spray adhesive because I seem to repair to many butts from guys which loosen up around the bottom hand. Also when a cord X pattern is used over a uncorked blank, the shrink wrap doesn't cinch down securely over a small blank diameter between the X's. When u use a larger diameter wrap than needed , you get a thicker rubber layer. Makes for a softer feel especially with cork base.
