I have some older model Penn Sentors, along with some smaller Penn casting reels, older from the 50's, 60's, 70's, but in great shape. I am a reel nut when it comes to old collectable Penn reels.

Would these types of Penns work, or are they too old? Do their reels with newer features offer any sugnificant advantages over their older reels.

Thanks again!

I have some Abu's (5000 - 6000) series reels and they are fine. I've come to personally like the Ugly Stick Catfish rod that was previously mentioned for 30 bucks, rigged up with a Penn no. 09 reel. You can find these Penns (or 9M reels) on Ebay for around 25-40 bucks. That's a 70 dollar combo. Best thing about the Penns, is that they are SOLID reels. They'll last a long time, if treated right. Not sure what kind of Penn's you have, but take a stab at throwing one the size of a 9 on one of those Ugly Stick Catfish rods (white rods with glow in the dark guides). The Tournament Choice rods for 12 bucks hold their own. I haven't tried the Pro Angler rods yet, but I've heard from a very trusted source that they are more than worth the price.
Here's a pic of my favorite rig:

Remember, it's all about personal preference. This is my main choice for a rig and I really dig it.
