hey guys, I was just wondering what you guys thought of the new active Heirs? I did a search and most of the posts were about the older passive models. Also what do you guys think of the buzz feiten system? Does it really improve intonation that much? And how much do you think I would expect to spend on the newer Heir 5 string? I'm really gassing for the red one with the rosewood fretboard (on the mtd website). Thanks a lot guys!
