If you are looking more for a glow, you can always try adjusting for character auras made available after level 30, rather than relying on power sets for "Da' Glow."
As for the sets themselves, Invulnerability seems to be most like a Golden Age secondary out of the three, thematically. If you can herd with the set then you can bring out its full potential.
Super Reflexes works too, though it is a late bloomer until you can get all your defensive powers and get them slotted up.
Dark Armor allows for multiple stunning when paired with MA, compared to the other sets.
So, I've deicded that I want to make a new MA/ Scrapper. My only problem is that I don't know what to pair it with.

I was looking at /SR, /DA, and /Invul. All three seem to have decently large end issues with DA being possibly the worst.
My Issues:
MA/SR seems like it's a bit over-used, but if it works, it works.
MA/Invul seems like it'd be the middle ground between SR and Dark, but it's not as bright as I thought it was. (Going for a "Golden Age" type Hero, glowing insanely while flip-kicking would be neat!
Ma/Dark would look really neat, the whole Kicking Shadow type thing. But I'm not sure how well other colors would look on it when i16 comes out.
Overall, I'm shooting for a classic "Golden Age" type Hero, but also "unique". I16 should help with that. (SR would be pretty boring color-wise, and Dark may look a bit art-project-y :P)
Any suggestions / playstyle advice / other options would be greatly appriciated!
