Ok so im not VIP anymore, cant afford it at the moment. So when i use the client with out mirror, how detectable is that to Jagex?

From my understanding the difference isn't very big. If there even is a difference at all.

Don't worry, I've used both and I haven't experienced more bans with stealth injection or anything like that.

ok cool. I was just wondering because you know how people were getting banned using HD client awhile back and how apparently RSBuddy shows different to jagex

I would say you're probably better off using Stealth Injection even with the option of both. Stealth is much more reliable so if you're using a solid script then there's less chance something messes up!
