I just went through this myself a few weeks ago
I drilled a mutant and it was too damn strong for me
I already had a Mars that was my go to ball on normal THS shots, and even some med volume sport patterns
I went with a Nomad pearl, and it is a great piece but certainly much less than a Mutant is
The cell Pearl in my opinion is much weaker than the Mutant is if drilled the same way,
theres a lot of room between a Nomad Pearl and Mutant Cell,
something like a Reign, or a Full Swing fits inbetween them
Im getting ready to drill a full swing up this week
Im looking for something above the Nomad Pearl and below the Mutant
but I want to do a solid so I decided on the full swing,
