For those who have done it, what pickups did you have success with?

I'm thinking of picking up these:

And then get a pair of lower output passives to squeeze in them. I've read success stories of the 8 string conversions, but my 7 has soapbars with high output ceramics in it currently.

I was looking into more paf styled like what Dimarzio offers. I know I would have to modify the covers, but Dimarzio bass plates don't look the the tabs will be easy to bend if needed.

I really want to get some alnico v equipped, or even alnico II, in this guitar.

For reference, it is a GC exclusive version of a Jackson JS22-7
