NO! Stanski hasn't got a clue...
Lets compare a blue dot from columbia, and an XXXL
The blue dot has a pancake weight block with not core... this ball has a plastic shell.. and will go dead straight, and might wrinkle a hair on scorch.
The xxxl has a plastic shell and a true high performance core.. and will actually let you command a late raction on medium dry for spares and 10 pins and such, and also gives you an unbelievable edge on those scorched dry back end shots you run into evey now and then.
The XXXL is by far the best spare ball and dry lane ball on the market.
It has everything to do with the core....
