Rock, with the Hex and Spell in mind, what do you want those balls to do once you polish them?
I would suggest the following considering what you are going to do with the Super Freak.
1-which ever ball gets more length now keep highly polished, anywhere from 1500 to 2000 or more. Use the Clean n Polish to achieve this. IF you use clean n polish and you decide you want more length yet, then try Neo Tac's Controll it.
2-which ever of the two is stronger and I would think it would be the Spell, You can do pretty much the same as you are going to do to the super freak, only once you put the clean n sheen on put a very light coat of clean n polish.
With this set up you will have a ball for almost every condition. Naturally you have to find the EXACT polish amount that fits your game and the lane conditions you are on. The Track Magic stuff is great.
As far as cleaners go--I like the clean n dull. I have been using it since November or so and it cleans just as good as the Neo Tac Hook it and it keeps the finish on the ball that is currently on it. Polished stay polished and dull stay dull. However, if you have a ball that is shined--but it is caused from lane oil and lack of cleaning the clean n dull will take the oil right off of it.
Goodluck. Any other questions, feel free to ask.
