I am willing to guess nearly 99% of bowlers have no need for the Taboo Spare as a strike ball. The OP has not stated any other ball in his arsenal nor has he stated his rev rate, rotation, tilt or speed. Based on him having a Taboo B/S and a Taboo Spare (the only balls he says he has) how can anyone tell the OP the ball would be a viable option?
If the OP wants a more detailed or better answer, he would need to provide the above information at a minimum for the more knowledgeable people on this website to make an informed recommendation. In reality, the OP's best option is to discuss this issue with his pro shop, the people who know his game and the conditions he will be bowling on the best.
