I am fishing for some info from Storm. Once I have it, I will be glad to share.
I do know that Storm always tries to time out a release for the start of the USBC Nationals. This means the staffers get first dibs on it around mid February and then it tends to be general release around March 1. This has been the MO in the past with Storm.
I do know if they do a hybrid of the Lucid cover (NRG with less texture) on the same weightblock, it should compliment the Defiant Soul very well as a "ball down". Everything about the Defiant Soul just reeks of "must have" for the Storm/RG crowd.
