Bear in mind, amigo, that board is the people who maintained the FULL-SIZE aircraft, not so much modelers. And IMO, when you're doing a build for a wrenchbender, you really want it to be as right as possible... this is pre-prod and test, so we still have a chance to get things fixed rather than fight with an expensive retool after.
Besides, with the accuracy capabilities of modern technology and better access to preserved airframes, there's just really no excuse on a new-tool kit anymore. It also helps to consider that most F-106 builders tend to have some affiliation with the aircraft, and when you've got a tie to a given subject any imperfections in a kit tend to stand out more. For example, I know one old Eagle crewchief who has a kit from every tool cut of the F-15, and can't build ANY because he sees ALL their imperfections...
