Should be a great combo! I went with both blazes just because I always go Evo 7 with Ibby swaps and figured the Blaze bridge is a little less hot and compressed so it sounds a bit more musical as a result. The Evo is awesome for the tight ass metal rhythm stuff though so it was a tough decision.
Noice man, congrats! As far as the stock pickup sounding like a specific real DiMarzio, no idea honestly. It sounds pretty good for a stock pickup (and being a generic "designed by ____" pickup at that) although like I mentioned in my NGD post the bobbins they used appear to be the same for both the neck and bridge pickups so the pole pieces don't line up 100% with the strings on the neck pickup. As far as it affecting the tone it doesn't seem to be hurting much, but it was something I noticed once I had mine in-hand. That being said, $150 for a set of real DiMarzios is an easy fix since I know the neck and bridge pickups are designed to land where they should on the real deal. I'm still enjoying it stock for the time being, I won't be sitting down to do the pickup swap until March anyways so it's not a biggie as far as I'm concerned right now.
