To get really technical, the reason you are avoiding the flip has to do with opening and closing tone holes and how that makes coordination problematic. When you lift a finger, the pitch changes as soon as the seal of the pad breaks. When you lower a finger, the pitch changes when the seal is completed. So if the fingers move absolutely together, there will be an intermediary note. Yes, between the ear, brain, muscle memory and practice you can get the timing down, but why expend that effort - with the potential that it will still break down - when there is a mechanical fix? Ask any oboe player if they would use a mechanical alternate fingering to play an F major arpeggio!
The alternates on sax are really pretty few compared to other ww's. Side C, forked F#, the three (or four) Bbs, and forked high F/E are the main ones. Learn where and why, practice them, and use them and it makes the technique easier.
