If you're looking for Hammer stuff for lighter conditions, either of the Vibes or the Pure Hammer will have to be the choice.
From what I've seen/heard, the Blue Vibe is a bit earlier and smoother than the purple, which is said to go longer and flip harder. I have the Blue Vibe, and while it's good on lighter, it's still not a ball for dry, at least not for me. I use mine when my other reactives begin reading the friction too early. Still, even at that point, it checks in the later midlane before making a fairly strong, sweeping arc on the back.
I also have owned both the Black and Burgundy Pure Hammers, but I only have the Burgundy right now. Again, I don't really think the ball fits the bill as a "dry lane" ball. It gets more length than the Vibe, but it still offers quite a strong move. The real strength of this ball, though, is the fact that it doesn't overhook through the deck. When it arrives in the pocket, it gets nice, controlled deflection, promoting very good carry.
So, I guess which ball you choose depends upon what part of the lane you're looking to control. If I had it to do over again, I'd take a purple vibe, place the pin above the bridge and the cg in a weaker position that promoted very controlled breakpoint movement. I just tend to feel that pearls work better for such situations. But, depending upon your game, the drilling and prep, you could theoretically use any of the balls listed here for lighter purposes.
