I bought some off brand from amazon.com. And they are a complete waste of money. But K&T Industries are really good as are Hobart's rods. Maybe I should shell out a couple extra bucks to try some Fleetwelds' out. I just became the proud owner of PowerArc 200. It'll be here in a couple days. To keep this on topic: Keeping those 70 series rods crispy dry also make a huge difference! I keep mine stored in dry heat at 155-180 normally (155-160*F).
