The rationale is simply, "would Leo be OK with it?" and nothing else. If they made a Tribute model of the JB, it would be a runaway best-seller. I do like the fact that BBE has been listening, and that the new M series has quick-change battery compartments. Gimme a #8 neck on one, and I'll take the MFD plunge. Meanwhile, I still dig my JB-2.
