I've used matches to shrink tubing for 45 yrs. It takes practice but it is quick and does a good job. Granted they didn't teach that process getting my EE degree and sometimes it tarnishes the tubing. I have four heat guns that do pvc pipe down to very small tubing. I use those when doing multiple joints. But for doing one or two joints, a match or a cigarette lighter is my first choice.
BTW, the best tubing has a glue coating on the inside wall. More expensive, but worth it in my opinion.
