You mainly need extra passes if you plan to drop into a fight and be a major player rather then spending your time looking for someplace safer to be (like behind a big strapping orc). And even then, you can try using chems instead of actual augmentations. Risk of addiction, but cheaper, and only use it when you really need it. Jazz and it's like can be effective since combats are typically over with quickly.
And if you go for face / smuggler / hacker, you can drop into full VR and get extra IPs on the matrix doing things like hacking into enemy smartlinks / drones / alarms / cyberlimbs, etc.
A Face/Smuggler should be ok I think. Mel's issue is being a Sammie / Face in a group already full of sammies and a face. Hence I'm contemplating a hacker or, perhaps more likely, a ripperdoc.
