Joe, what level are you? Is there a real reason you want to boost T05. I don't believe making it softer is a real reason. If it is for that, you should get a softer rubber.
Unless you are a really really high level, there is probably not a valid reason for boosting T05. And booster, particularly more than a little booster, does kind of mess up spring sponge type rubbers like Tenergy and T05 really does not need booster.
Harder, Chinese rubbers like H3 are made to be boosted. T05, with it's delicate sponge is made to play as if it was already boosted when it was not.
If you want to mess around with boosting, get inexpensive Chinese rubbers like H3 and mess around. Those rubbers are excellent when boosted and only cost $20.00 for the commercial version so, if you mess up, you did not put such a big dent in your wallet and a few weeks later, the mess up will be gone and you can try again. It won't destroy H3 to mess up when boosting. It will do that to T05.
