Iketown,
I have a S&A, and a Hercules. Am having outstanding success with the control drill on my Herc and a length and flip drill on the S& A. Having said that, I would suggest you go with the 5x5 drilling, or something close to it. The motor (core)in the Sahara is still genuine MoRich!! It's still gonna do it's thing and do it strongly. That's why I've been having so much success with the weaker drills.
Now all I have to do is add and subtract hand to get a completely different look from these balls, but with that outstanding MoRich carry! Put the onus on the coverstock to get you to the door....and then let the core bust it open!
Just my take.
