I was wondering what time of year is good for swimbaits suck as Keitech's? 

Anytime the fish are feeding heavy on shad. I'd say a pretty effective bait spring thru fall.

I throw EVERYTIME I am on the water!

Year round... Retrieves change depending on the season.  My Avatar picture iis a pair of Keitech fish from August.

d**n, I'm screwed, there ain't no shad nowhere in 2000+ miles around.

Depends mainly on the depth you fish your swimbaits, and whether you're fishing a natural lake

or manmade impoundment. Personally, I only fish swimbaits as a subsurface lure,

and turn to other lures to cover the midwater zone (of course, they may be fished from top to bottom).

Kool, thata mean I ain't screwed.

i throw swimbaits like that a lot year round, slow down to a bottom crawl in winter sometimes but still fishes great,

 

 

I fish the keitech year round.  I have been doing very well in the winter with this bait and have had luck on them when nothing else is working.  I use the owner twist lock weighted hook and put them right into the cover.  It seems as though i can get two actions out of them, a worm type when i toss it in, and a swim-bait when i retrieve them back out.  No other small paddle tail has worked as well for me like this and in the very cold water that is going on right now.  The scent may have a lot to do with my success because i dont ever add a scent but who knows.  I fish the same 4" swing impact behind a jig in the spring and summer to get the larger profile which keeps me from having to buy a lot of different types.  I also use the 4.8 fat in the summer to up-size and the 3" to dropshot.  Ayu works the best for me, and is all that i buy now.

All year.

Whenever you want to catch bass.
