Can anyone tell me about these Dean Markley strings?

Okay, so a few months ago I got a free set of strings from Guitar Center. The problem is, I can't find a thing about them!

I was thinking about putting them on my Spector Legend, but first I wanna know if it'll be an improvement (I think I'm getting close to the stage where I should consider new strings, but it's probably not nessicarey). Anyway, I'll on the package at the top it says "High Gain Series". The guage says ML 45-105. Below that is #8864. Can anyone help me?

I got a set of these at GC to. I think they cost $9, and the Markley site doesn't even mention 'em. Might be a discontinued item.
