both are awesome. Betti's shape is very appealing to my eye, Byron for a copper is going to be much cheaper, still be awesome, and he is a one man show so you get to deal with and customize more with him. Plus, he's an awesome guy. Make sure you look at Mannkrafted, Xenon, Lajosi, and Tad Moore as well, those plus betti and Byron make the best 8802 style IMO.
