I just picked up a nice 70's Penn Senator 3/0 rod at a yard sale for $5. It had a couple bad eyes, and rusty rollers. I had the eyes replaced, and I replaced all the rollers. Now I have a nice rod for under $35. I plan to use this rod offshore for Tuna, the 3-4 times a year my father in law and I go. I was going to buy it a matching 3/0 Penn reel on ebay, but my father-in-law says thats too small, I should buy a 4/0 or a 6/0. I'd think a 3/0 rod should use a 3/0 reel, but I figured I'd ask. The rod says 20-40lb line.
