Ok heres the deal.. i fish a small walking bridge leading to an island, it is about 25 yards long and it is about 10-20 feet deep with alot of christmas trees and the water is stained. i get most bass jiggin a worm off the bottom, but they arnt the biggist of bass, probably about a pound and a half...any suggestions on what i could use or what presentations i could use to catch the bigger fiah or to catch more fish? thanks

what kind of worms are you using?  you may try upsizing your worms a little.  it will probably knock down the number of fish you are catching, but should help in getting some bigger bass to strike.

Use a jig

Totally agree with Chris on the jig.Another thought is you made need to slow down your presentation and don't make erratic twitches or jerks.Try just dragging a jig real slow with pauses.If you don't get nothin  dragging,make single hops and pause it for atleast 5 seconds.
