If you check the Cyclone review, I'm pretty sure Chris used the IG Rad OS for that test and had the tension at 52#, I assume the RPM would go in at a similar tension. He also suggested starting out with lead a 3 and 9 with an equal amount at the top of the grip to maintain the original balance.
Let me know what works for you in terms of adding lead. I've got 2g at each of 3 and 9, and 4g at 12 right now. With an overgrip the balance is 4 HL which is what I like, so I didn't bother putting any weight down by the grip.
Thanks Tommy, much appreciated. I am tempted to stick a leather grip on too if I add lead. Is that your final set-up or are you still tinkering? I will go RPM Blast 17 at 55lbs and see how that goes.
