I made a quick build for you. I kept stealth and added a stealth IO to stack with it for complete invisibility. You're just over soft capped defense even when stealth is suppressed so elude isn't needed in this build. Also added aid self for the situations where a few hits just get through and to reduce downtime, although you have quite a lot of regen with this build.
I expect this build will cost quite a lot but if you've sold all the IOs/salvage you've got to date I'd think you have quite a stack of influence hidden somewhere 
Normally I'd use the short export form which I think is a lot more clear but since you dont have Mid's this might be better to see what sets you will need.

Exellent thanks for putting this together for me, i wouldn't have had a clue as to what IO's to slot 
Just one thing would switching combat jumping and super jump for air superiority and fly have an adverse affect, as i would prefer fly as my travel power ?
Many thanks

Well, you'd lose the ~2% def from combat jumping so then you'd be a bit under the soft cap when stealth is suppressed. This shouldnt be too hard to fix, just needs shuffling of a few slots.

Actually scratch that, i will keep super jump as my travel power, i just remembered how slow fly was when it was unslotted, and seeing as i dont have the slots to spare it's super jump ftw 
Thanks again
Twisted
No problem

Ok guys i need help rebuilding my first ever lvl 50 toon, i haven't played him in ages (been busy redside) now i want to get back into the hero side of things.
I made this toon way back in the day when i first started playing and before ED came along he was a god with perma elude, then ED was introduced and i moved a few slots around but he was nowhere as good as he was so i shelved him
Now that we have IO sets i hope he can be fun again, but here lies the problem, i have never slotted an IO enhancement in any of my toons ever, and to be honest i dont know the first thing about IO slotting, even though i have been playing for 4 years on and off i have never even made one, i just sell all the salvage and recipe drops i get it's sad i know
So can anyone help me with a new build for him ?
Here's what he looks like at the moment, sorry it's in pics and not the fancy hero builder format that i see everywhere but i have never used one of those either
