There are three categories I will address in this topic:

Oil Absorption Rate
Chemical/Mechanical Landscape
Overall Strength

The overall strength of a coverstock is dependent on several factors, but the primary ones are Chemical/Mechanical Landscape(Ra + Rs) and Oil Absorption Rate. Most will be primarily concerned with overall performance, but rating the covers with the other factors will provide some insight into the how and why.

All ratings are from strongest or roughest, to weakest or smoothest.

Oil Absorption Rate(OAR)

Formula 5
Motivator-T
Motivator-R
Vicious
Motivator-Z
Motivator-X


Chemical/Mechanical Landscape(CML)

Vicious
Formula 5
Motivator-T
Motivator-R
Motivator-Z
Motivator-X


Overall Strength(OS)

Vicious
Formula 5
Motivator-T
Motivator-R
Motivator-Z
Motivator-X

Noob question without googleing, what does Chemical Landscape mean?

Regardless, great post, the OAR is something I definitely needed to know.

Chemical landscape is the inherently formulated microscopic roughness of the coverstock. This goes beyond surface preparation into the actual Ra and Rs.

Ra is Average Roughness.
Rs is Surface Roughness.

So, in other words, technology and chemistry is marching on. Motiv has found a way to make the surface texture rougher (as compared to previous iterations) without making it more porous? I had read somewhere that as the urethane cures, the chains of polyols intertwine and interconnect in a way so as to make the entire cover one giant chain of urethane. What this says to me is that they have chemically found a way to make that chain fold back on itself in specific and predictable ways to create this surface profile. Am I anywhere close? I'm no plastics engineer, but this stuff is interesting. What makes it tough to learn about away from the factory is that all of these techniques and additives are closely guarded, proprietary secrets. Not a lot on Wikipedia about plastics chemistry.

The real bleeding edge molecule bending engineers work for BASF, Bayer, HK, MobilChemical and other polychem companies. The bowling companies additive packages are the proprietary secrets, the base urethane resins are suprisingly very similar. There are variances in base formula, but the real magic happens within those additive packages.

It is a bit analogous to cars. You have a Lancer Evolution base vehice, and several companies making tunes for it. Some tuning packages are better than others, and some do things in different ways. Some are the fastest on the track but blow up in a short time and always need to be rebuilt. Some are engineered very well and perform as expected for quite some time, providing predictable and reliable performance. Some blow a bunch of NOS to try and overcome design deficiencies.

Justin. If you have time can you come up with an updated list of motiv coverstocks strongest to weakest. I am specifically interested in the differences between the Motivator T and the atomix coverstocks

questionn also posted here http://forum.bowlingchat.net/posting.php?mode=edit&f=6&p=49744

I'll update this in the next couple of days.

I'm gonna drill up a 2 cruel and a plugged primal. I would be interested in the differences between the whiplash cover vs the vicious cover
