I fish where there's not a lot of cover just grass and hydrilla and such and was wondering what kind of rod I should get for plastics t rig and jigs anything with a single hook basicly I was thinking anything 7foot and above medium heavy extra or extra fast any input

MH/F is about the most versatile casting rod you can find for bass fishing. Keep in mind that the terms used to describe or "rate" rods is subjective. Asking here about specific models combined with some trial and error on your part will get you where you want to go. 

What sounds like a good rod thats in the 200 dollar range I can't find any fast action rods just extra fast

I like St Croix Rods for over the counter stuff. They have an extensive line up to cover any use you can think of and are quality rods. The Rage line is built on a very good blank and priced right: 

RC71MHF 7'1" MH Fast 1 12 - 20 3/8 - 1 4.6 1 $ 150

The Avid is the same blank with cork grips and I think different guides:

 

AVC70MHF 7' MH Fast 1 12 - 20 3/8 - 1  4.7 2 $ 200

For areas without much vegetation I fish light or med light.  If it's thicker I'll fish med and once in a while mh.

Is there really any difference between extra fast and fast where I fish theres a lot of grass and I mean a lot I found some rods I really like like the Powell endurance 7'3 mh extra fast but again it's extra fast I just want an action that's most versatile with t rigs plastics jigs and such I heard people shy away from extra fast why
