I never thought I'd post here - but I have the hands on a single drill Blue Hammer in very good shape (Yeah, ebay). As far as I know, it is urethane with the classic Hammer core - and it has good rep!

I suppose it is good for medium shots today - does anyone still use one and share impressions? There are no reviews on this piece at BR.com, so any input would be gladly appreciated.

Besides, does anyone know the RG differential of the core? I am not sure if it is the same 0.04 as in the later Blades?

Thanks a lot in advance!

Ball is great for short, dry or big over-under conditions. Don't know the rg dif but i can get my to flare 1 1.5 in. I still have 2 of them that i use for second shift in my travel league and i have even used one on the Viper pattern in my PBA league. It didn't over react on the back and had plenty of punch until we carried the oil down then i could go to a reactive. Hope this helps.
