The SMOKE is two things. it is:
1. Very mild coverstock
2. "Old School" three piece pancake core.
It is going to be just about as weak as you will find in any reactive resin ball.
I have an old reactive "CLAW" Hammer that would be comparable to the SMOKE, and it is a lifesaver when I need that ball to fill the gap between stronger reactives and weaker urethanes.
