I emailed Brian Graham from ebonite and asked him about the new hammers comming out. We were right about all but the vibe. This is what he said:

You are correct about all the new Hammer balls except for the Vibe.  The Vibe features a performance core and a new pearlized reactive coverstock and is a good match on medium to dry lane conditions.  The Big Rig Diesel, Razor Blade, and Vibe will be available in pro shops in early June, and the Hawg and Pure Hammer will be available in late July.


Im guessing the vibe is an addition to the rev line up

i heard from someone that the Razor Blade will have a new core, similar to the prigional hammer core with the flip block, but that it is modified in some way. IDK, but i cant wait to see these new releases!

From the pictures that I've seen so far, it looks like the Hawg has the same core as the Big Block Diesel.  I personally don't know of the performance of the BBD, but I could imagine that the pairing of the BBD core with the Cut-Throat coverstock would make the Hawg awesome in the oil.

I wonder how the Hawg will compare against the Real Deal or the Big Deal

yea plan to buy two of them hawg and razor blade already got big block diesel love that ball on dry conditions it rocks!
