Just by surface and coverstock I would have to say the guantlet would retain more energy.
Many have polished their sure lock with good success.
U can't miss with either it seems.
The sure lock is more of a solid
The guantlet looks to be more hybrid (more length)
Neither should be allergic to oil.
I really can't miss either ball....
To me it's more virtual gravity (sure lock) versus Critical theory (gauntlet). More often than not the virtual matched up best on heavier shots. The Critical would have its moments...But not be my go to.
My vote is surelock, but u cant miss with either...
