The issue with air getting into the system with Saint is the "free stroke" screw that when turned out, allows air to enter.
I'm not a huge fan of the lever ergonomics (I'll swap my old M810 levers for the new M820 to cure the problem) and I also find that the lever gets all wonky when the pads wear very thin (I like to get every last bit of material out of my pads). But overall, despite its shortcomings, is the best brake out there.
You're not a very good saleman….lol.
Like I say, for some the Saint is awesome and some hate them.
I'll stick with my Hopes for now.Not saying they are the best out there…but for me I like em.
