I've seen a lot of guys catching some pretty nice bass around my area on swimbaits. I don't know what size or type they are using, but I haven't ever had any success on them, and not much experience fishing them. Any suggestions on where to start? I've heard a little about reflexion swimbaits. I don't know whether to use hard body or soft body, size, and what colors/patterns to go with. Any advice is welcomed. 

There are swimbaits and wannabe swimbaits, soft swimmers, hard hand made and mass produced injection molded hard swimbaits. Big,medium and small swimbaits, lots of choices and easy to make a mistake.

Are you willing to invest in specific rods for the heavier swimbaits over 2 oz? If not;

My suggestion would be to start with Black Dogs G2 bluegill wake bait or Matt lures 5" soft bluegill slow sink.

You will need a med/ hvy or hvy swimbait rod for the larger heavier swimbaits.

The top soft small swimbait IMO are Little Crippers 6" Trash Fish and Basstrix 6" Hollowbody swimbaits. Both these lures started the small to medium size soft swimbait era and have lots of knock offs, the real thing works better. Large keel weighted hooks in 6/0 work for both and these can be fished OK with heavy frog or jig rod.

Swimbaits are not crankbaits, this is the mistake most anglers make, chuck and wind like a crank. Swimbaits are like fishing a top water except underwater; slow and steady is best most of the time with a few pauses and jerks to change pace.

Be patient and give them a full days work out.

Have a good and safe Memorial Dat.

I like soft body swimbaits, I also like them weedless but some swimbaits are not weedless so you have to modify it yourself. I fish my swimbaits (VERY SLOW) because I am fishing 8+ inch swimbaits. And you need a strong rod with alot of backbone. I use my flippin and punching rod for swimbaits 

I started fishing bigger swimbaits with a 7" MS Slammer and still fish it often. It fishes easy, isn't super heavy, and it moves and catches a ton of fish of all sizes. They aren't super expensive either.
