Which arm implants should I get as a stealth netrunner?

As the title says I'm a stealth netrunner, I'm really wondering which arm implants I should get, I have monowire right now and the perks for it but I never r actually use it since my main weapons are a silenced pistol or a sniper. I feel like I could be more effective if I refunded the monowire perks and got cyberwear I actually used in combat, but there's not really any arm implants that specialize in stealth.

I'm thinking I could get the projectile launch system for when I actually do get into fights or gorrila arms so I don't need to spend points that I would be putting in intelligence or coolness into body. Lmk if there's some stealthy use of monowire or mantis blades I'm overlooking please!
