i simply have no idea man. my experience with guitars and pickups have so far been quite limited.. stuff I tried - Custom Staggered, JB Jr, Super Distortion, PAF Pro, Screaming Demon, Invader, Hot Rails. And on certain guitar woods and certain pickup positions only
All I can say is Invader would be bass heavy and I suppose very subjective in terms of tone. You like it or you hate it.
As for HS-2 I've watched Randolf use it on his Yamaha and I must say it's REALLY very good for cleans, considering it's not even a true singlecoil. Little quack or twang heard though. (Which I think you won't be interested since your preference is towards metal.).
well the next best thing i can do:

the SD forums are free for registration. Just post up your setup and inquire whether it's a good match. there're so many players there and they'll be more than likely to give you good advice.
