jw,
I saw in another post that this ball is a urethane.
AS far as I know, Delayed Reaction reduces the hook and backend on RESIN balls because it reduces its ability to absorb oil. Urethanes do absorb oil but significantly slower than resin balls. The ratio used to be 20:1, but with today's oil sucking resins, that ratio may be even higher.
The SBG has a regular dynamic core and its hook is more closely related, I BELIEVE, to the fact that the flare exposes clean surfaces (without oil) to the lane surface. The oil should sit on the surface for a good long time, enabling you to easily wipe it away.
So, I believe that the only effect you get from using Delayed Reaction is that of polish - adding shine/gloss to the balls' cover. What you want may be better achieved by using an abrasive polish, like Storm's XTra Shine. It will add shine but will also smooth out the coverstock. You could also try to sand the SBG to 4000 grit Abralon and then add polish. (I did this recently to a friend's SBG. It is HARD work. That cover is hard.)
Good luck.
