I use the ernie balls, 9 or 10s , either way. And i like Elixir too but those are a hell of alot more expensive, and the difference in quality isnt worth the difference in price.

The strings that my BC rich 'Ice' Acrylic Warlock came with are really awesome, but i have no clue what they are. i'd use the top and bottom ernie ball strings and then the rest would be the ones that came stock, if i knew what they were.
