Charlest,
My understanding is the Perfect is a Particle pearl, not resin pearl. The website states Flex Molecular Additive . Isnt this LM version of particle? The RG and differential #s are pretty close also...I also kept my RSP polished and could use it on a lot of conditions polished. I am new to LM and wanted some input from someone who maybe had experience throwing both balls. Thank you
Todd
Todd,
I don't know what "Flex Molecular" stands for or is intended to mean. Since I am rev dominant, and seem to be able to use the Perfect on medium-light oil to start with and can take it down into where the oil deteriorates into light oil, I suspect the cover is regular resin; if it does have particles in it of some sort, they would seem to be relatively weak. The lanes were quite dry (by my standards) before I couldn't get the ball through the heads.
I have not yet tried the ball dull, even as mild as 4000 grit.
Yes, the core specs are similar. I had the RS-X, the solid resin version of the RS series and threw a friend's RS-P briefly. The RS-P was much, much earlier than the RS-X. In its stock form, 800 grit dull, it required lots of head oil to perform. The Perfect seems to require much less.
