Judging by your guitars you're probably into your metal, which means you probably use some lower tunings ie drop D, drop C, drop A# etc. if this is the case I highly recommend the following:

I recently tried them over my usual Beefy slinkys and/or Not even slinkys and havn't turned back. Nice heavyish bottom strings for those heavy metal riffs with some nice light top strings for the shredding/soloing ? . Seems to work well together haven't had any problems. I use the Ernie Balls just because they're easy to get a hold of, the D'Addarios of the same Gauge should work just as well, perhaps even better.
