I strongly recommend Tactics for Advanced Players by Averbach. It covers all phases of the game, and he has some nice tricks, like on calculationing or keys squares, that cuts down the options to look at in a position. It'll add some heat to your game.
what tactic book help u get over that hump

Okay, I've ordered this:
Tactics for Advanced Players by Averbach,
and this,

For a beginner (me), this site is overwhelming, Some of the video lessons are overhelming. The number of teaching tools is overwhelming. This thread is definitly overwhelming.

I have the program bundle that I mentioned above for improving my tactics. It contains 3 complete programs. The good thing is that it offers us the option to solve tactics classified by theme and delve into the themes. After gaining some experience you can choose to solve mixed tests and define the rating range of the tests. My opinion is that studying tactics from books is somehow slow. I prefer books mostly for studying openings.

Litwitlou: I'll join SkyMarshal in recommending Susan Polgar's "Tactics for Champions."
The problems are easier than most tactical puzzle books, but not brain-dead. That's a feature IMO. The problems are arranged by themes.
I want to be good enough to spot basic 2-3 move combinations reliably, not become a tactical wizard at solving Puzzle of the Day positions. Polgar's book is the best I've seen for this level.

I love all the computer options for chess learning these days. However, books still have their virtures, especially a chess tactics book.
I carry one around with me much of the time and in spare moments, I can flip the book open to a problem and start work on it within seconds.

It's enlightening to go over a lot of chess.com games and see how often straightforward tactics are missed by class players even at slow time controls.

Duffer question. ct-art?
Its tactics software. Very good sofware
Very good indeed. I have it since January (together with other 2 of their products) and my tactical vision is already boosted.

Yes, I spent some time on that site. But I really have to study it before purchasing.
I'm in a bind. I'm serious about improving, so I'm willing to spend some bucks. But I don't have enough bucks to buy the wrong stuff. So I need to be picky.
You guys are a great help, thanks again.

USCF A player that didnt start studying tactics til about 3 months ago. So yea tactics arent everything.
Back in the sixties and seventies and before, no USCF players studied tactics beyond looking at a monthly puzzle page or picking up an occasional book on combinations.
You can pick up tactics without drilling on them. It's just slower.
Litwitlou- go to Dan Heisman website and you'll find it on his recommended book page. thats where i get all my info. its just after i finished his recommended tactic books for beginners, the other books were to advance.
Thanks very much.
