i'd prolly go with the bomby regs just cuz you get more for ur $$ and if you have to make some of that cash back, you can alwase resell it, but the sour diesel will prolly go farther as it is better bud in my opinion, and im sure every1 else's, so it's all a matter of which you'd like more...you should treat yourself and go with the sour diesel tho...good shit
