I've been looking into a Lakland 4 and Cirrus 4. I did a search on this and came up with some answers, but I would like some others' opinions too. 1. What's the difference (sound, quality, etc.) between a BXP and regular Cirrus? Can you actually tell a difference, or is it more like a Skyline/US difference where it doesn't matter so much? 2. I know they're a lot different, but if you had to pick one of the 3 and ONLY that one along with a Bob Glaub as your only 2 basses, which would you do: Darryl Jones 4, Cirrus 4, Cirrus BXP 4 ? Sorry for all the questions, but I do not have access to these basses here.
