The Mission Unknown is a harder surface. I took it as low as 1000 grit for nationals last year and it didn't handle oil well. It also lane shines up quickly.
Keeping surface closer to 4000 the ball has been a must have anywhere I go.
Thanks for the reply. I got this ball last summer but, due to an attack of arthritis in both wrists, I was unable to try it until recently. In the box finish the ball did nothing for me. That's the reason for the question. If you are using it at 4000 does that mean you use it on medium to dry conditions? Also, if you tried it at 1000 and it didn't handle oil well, I may have to change my idea on how to use this ball. I have an Ebonite Warrior Elite that is almost too strong on anything but very heavy oil and I was hoping that the Unknown would give me something just under that and something I could control on a fairly oily condition.
Keep in mind that is what was best for me. I use to apply 2000 to it regularly as my favorite finish. Then changed to 4000 more recently.
If it were me, I'd try going to a fresh 2000 see what happens. Not enough then try fresh 1000. Still not enough then go 500/2000. You can't hurt anything in doing so. I would go 500/2000/4000 after several games to get back a little more reaction from doing just 2000 or 4000 for so long. That is usually with a de-oil as well.
I typically use the ball as a step down from my Warrior Supreme. Now that I use my Gauntlet(original) a lot more I use it has a step down from it. When I need to move in and have a ball more responsive down lane it is the go to ball. It can handle medium to lighter oil really well. Then when I need something with the same shape but retains more energy I go down to my Rebel(pearl). Same ball motion just better as the oil starts to thin away up front and the Unknown is losing too much energy early.
