PressuredFishing

A good starting lure, you will hear guys say spinnerbaits or crankbaits, maybe even a chatterbait. I would reccomend choosing the lure based on a multitude of reasons
 
1. Forage
2. Water clarity
3. Speed of retrieve
4. Temperature
5. Light conditions
6.wind/current
 
There are hundreds of videos, But in a nutshell dirtier water  overcast/rainy windy conditions in spring-fall do better with more rackety lures, and clear, bright, no wind days do better with more natural and subtle baits. Colder weather usually means slow, hotter normally means fast. This is all just theory though. Finally think about what you are fishing through so you snag less
 
grass: Swimjigs spinnerbaits and chatterbaitsswimbaits come through grass decently
 
Wood: squarebill crankbaits spinnerbaits and swimbaits come through wood well
 
Rock: squarebills, spinnerbaits, swimbaits, jerkbaits come through well
 
Topwaters can be intimidating but they come through all submerged cover well.
Open water: everything can work but I really like baits with treble hooks because the hookup ratio is nice.

100 150 200, and 300 CT are IN A NUTSHELL (I understand there are slight differences lol) the same reel but different sizes. 100 is a great standard jack of all trades baitcast reel. the 150 holds a tad extra line and is meant for bigger lures or lures that have resistance like DD cranks, big squarebills, A rigs, tiny swimbaits like a s waver 120, frogging, and pitching/flipping. The size 200 and 300 are ideal for smaller swimbaits, the 200 handles smaller 2-4 oz swimbaits and the 300 is a more well rounded one for swimbaits, similar to a lexa 300 but not as big These are also ideal for inshore saltwater and can cast heavier weights off the beach effectivley. Yes they make it complicated but it is a nice feature that diawa offers so you can choose the best sized reel.
 
As for SV and TW or SV TW reels, its an upgrade or a more beefed up version of the tatulas. TW stands for T wing, and SV is in a nutshell a upgraded spool, on a short shaft that is effective at throwing lighter lures beecause the spool is lighter.

Okay, so depending on the size of catfish, you will choose your combo, 1-30 pound catfish can be caught on normal bass low profile casting setups, you don't really need a new setup, or an expensive setup for catfish. However If you don't want to get your bass setups slimey, I understand. You also don't need super heavy Gear unless your going after bigger fish. 12-20 pound mono works fine or any braid, catfish could care less about line. For the rod, you can get a Medium heavy shakesphere ugly stick, it will last forever and you don't need sensitivity for catfish. When using mono you can opt for the colored lines, like yellow or gold, just so you have something to watch in the water, you can also get bite alarms OR a bait clicker. For reels any low profile reel will work fine, tons solid reels, you can choose your likings. If you prefer spinning a medium heavy OR medium ugly stick will work fine for spinning, with spinning equipment you can throw Weightless chunk bait which can sit above summertime grass. Also most spinning reels have a audible clicker you you can set it loose and you will hear a fish on the line.

I have noticed spinnerbaits have taken a fall out period, so many lures similar, like underspins, so many moving baits, the one thing I do like about spinnerbaits is the skirt and getting it to pulse.
