I have an 02' vanilla and an 03' Float
TALAS stands for Travel Adjustable Liniar Air Spring.
So the two forks you are talking about are the Vanilla and the Float.
Vanilla is coil, feels like coil, very stiff and rides great, with a lockout it's a great fork for a bike with coil/coil (my opinion is always match coil/coil or air/air, it just makes a bike "feel" better, just my opinion)
Float is air sprung, feels very close to my Vanilla, but "still feels" like an air fork. If you do a lot of steep, long mountain uphill grinds and must have the adjustable travel, maybe the Float is best for you. If your bike is setup with the geomerty to allow 4 or 5 inch travel fork and still climb well with a lockout, and you want to have a coil/coil setup, go with the Vanilla.
I like them both, it's somewhat personal opinion as to what "YOU" will like best.
