I think you are in trouble expecting to find a ball that will hook for you if your Fury and Hawg don't.  Before buying a new ball I'd play with the surfaces on a few of the ones you have already.  

If you are going to get a new ball the first thing I'd look at is how the current equipment fails to react.  Is it not hooking soon enough or is it hooking but not sharp enough at the end?  If it isn't soon enough, by going to a layout with the pin in the center of the grip you can get it to start into a roll much sooner, but you will probably create a shot with a gentle curve for a ball path.  Trouble is if you choose a ball and layout for a snappier backend reaction that promotes skid first, with your longer oil it may skid right through the pin deck waiting to find enough dry to move.  

If your old equipment is just plain worn out then a new ball will do wonders but the stuff you list in your arsenal is all fairly new so unless you bowl a lot it should still be serviceable.  I really don't think any of the balls you list as at the pro shop will be that much of an improvement over what you already have.

Thanks for the replies.  As for surface prep, I have tried various surfaces for the Fury and Hawg and they are at 500 now for oil.  The Hawg seems best for oil right now but still have to play it tight.  

Strider, you mentioned that I needed more variety, so what do you suggest?  I do have equipment for drier lanes, but have not used them in any of the tournaments that I have bowled in.

Not many games (got back into bowling this Jan.) and they are taken care of religously.  Monthly they get the CnD treatment and cleaned after each set.  

I would still like to add another strong ball for heavy oil.  Any suggestions?

Like I alluded to earlier, the ones you mentioned won't handle more oil than what you already have.  If you want something stronger, look at the Brunswick Mammoth, Columbia Resurgence, MoRich LevRG, or Visionary Centaur AMB Particle (my choice).  Legends/Lanemasters probably have a good choice or two, but I don't know their line well enough to suggest anything.  I don't know what is available to you, but if you're going to spend some bucks on a new ball, make sure it will be what you need.

out of the ones you listed, anger I think would be the best or black widow. Not sure about roto grip never used their stuff and secret agent is not what I would consider a heavy oil ball. Really what you need is a very dull ball with lots of roll in the mid lane if you are playing on a long pattern. The black widow and secret agent balls are go long and come back strong on the backend.
