for comparison sake, yes
the orange ball was originally pin down and the reaction is not what i wanted
went pin up and then adjusted surfaces
even though i have an adjustable speed spinner and all of the powerhouse products
i dont think i was able to replicate the factory surface
So my comparison might be a little flawed as I have not touched the black balls surface
but, i do know that the black one has the added length and motion that has worked well so far.
the orange one didnt seem to go quite as far down the lane for me.
its a minor observation at this point as I do know other people that love the orange 1
i would say that if you are rev dominant, you may want to think about a layout that will get it further down the lane, store some more energy
IMO, i can adjust more easily to late read than early read
