I have a 215 based on the TL606 design, but I've been really interested in a dually or two lately because the weight reduction would be nice. Are there any real tonal benefits outside of lower weight? I've also considered the fEarful style 215 (or fEarless? I can't remember) but I'm not usually a fan of tweeters. For reference, I tune to C# standard and play everything from hardcore punk to country to R&B with a P-Bass, 800RB, a V4, and a Marshall Plexi.
