Well good luck in your pursuit, for a bottom fishin spinning reel,....... I would first want a saltwater reel. I have no experience with the penn spinning reel, but would think it is a good choice. My experience is this:
The reel I have used for the last few years with great luck is.......you guessed it Quantam laugh , it is a blue runner, been used in salt and fresh for lots of fishies.........BUT!!.. I switched to Okumas wink , as I like the 10 ball bearings in my metaloid.Now all of my newest spinning reels are Okuma!
They are bar none the best for the price! (IMO)
The quantam held up nicely, and still use it for sturgeon eek , and back up heavy set up!

So on that note I can tell you I would rate in this order.... from experience ..other than quantam (know you dont want one)
1. Okuma (metaloid,epix)
2. Shimano (alot of good reels)
3. Unnamed reel

Hope that helps cool
