Gigged last weekend with my ash American Series HSS strat, loaded with VHII and Mother's Milk, thru an Orange Rockerverb/2x12 cab and the VHII is just stellar. Crunchy, punchy, touchsensitive, good bass, enough mids and a clear topend that is not brittle or too bright. I love the dynamics of this pickup, the amount of pickattack makes really a lot of difference. I'm sure the VHII can do metalstyles too. It's tight enough.
The BD is somehow not connected with strats here. I don't know why. I have a Crawler in another swampash HSS-strat and that one is very versatile, just not really a metalpickup. I guess the BD would work in a strat too, but don't have any experience with this pickup.
