Dreaming of new lenses....

So I'm mulling over buying some new glass to add for my wedding gigs and upcoming June West coast photo adventure. On my mind are super-wides and primes. In particular, I 'm looking at the Tokinas 11-16 f2.8 and 12-24 f4. I really like the speed of f2.8 but the 11-16 focal range is a tad limiting. I like the 12-24 because it overlaps (partially) my 17-50, but the f4 is limiting as well. On the flip side, a $200 Nikon 35 f1.8 is very appealing as a backup for weddings..... If only I could buy all of them!! I'll play it over another day or so and then make my move....
