I was thinking of getting an abu garcia vendetta casting rod in medium heavy or heavy action but not to sure which one can someone explain which one you would need for different situation . If it helps I using is as a flipping and pitching rod , also I going to fish in brush piles, grass beds and weed lines . So which action is better for flippin these and why ?

The  "Action" you are refering too is actually the power of the rod . Both of the rods you have listed are fast action rods.

For flipping I would go with the heavy power , fast action rod. JMHO

I would recommend the MH if you are doing basic flippin'/pitchin' and the H if you are punching mats and other heavy vegetation.  The H feels significantly heavier and significantly stiffer.  I flip and pitch a lot and I returned the H for an MH because the H felt like a broomstick.

x2 H only for punching you will want something a little softer for basic pitching.

X3  I'm buying the H either this week or next week so I will tell you how it feels if I buy one before you do.

I used the 7'3" H/XF for pitchin' into the same situations you listed.  It was good, but a tad heavy (literally, not power-wise).  This year I went with a much more balanced Kistler Helium II LTX 7'6" (Heavy action, soft tip though).

The Vendetta in H/F or MH/F... I'd probably recommend the MH/F as it'll still have plenty of backbone to pull fish out of nasty cover (mats), but the other 99% of the time it'll be better for your intended purposes (weedlines, grass, brush).
