By cons not at all agree for the flexibility of Modiano Texas Poker, how can they be more Flex than Kem's ?
The flex scale as measured the way it gets measured is not "linear" in scale to what you would be able to feel.
In other words, if you were to flex a "soft" Cartamundi Classic (20) and then a "stiff" Faded Spade (12), you would normally expect something with a flex of 16 to be "medium", that's the way we stupid humans think. But, that's not the physics behind the way gravity & other properties at play works. Hence, the scale isn't linear.
"Medium" in feel to us humans is about 14-14.5. Which I noted in the explanations below the table....
FLEX: As measured in degrees on the Flex-O-Meter of Truth (new/unused card)
20 = Soft
17 = Medium Soft
14 = Medium
11 = Stiff
What that means is, if you hold a "12" & a "13" one in each hand, you can actually feel a slight difference. But, by the time you get to 19 & 20 you'd be hard pressed to tell the difference just by feel alone.
Take a look at Modiano's Texas Poker & Jason's older Desjgn decks. Jason has stated that his older Modiano produced decks are made on the same stock as the Texas Poker line... so, any difference between them comes down to the printing process & normal manufacturing tolerance.
& when it comes to Modiano, I've found that "tolerance" to be somewhat wider than many others.
At any rate, do they flex "more" than Kem.... technically yes, just slightly.... obviously proven.... but, as far as flex feel between them, it as much as makes no difference. & you can throw Gemaco & Copag in that same "soft" group as well.
The Platinum line on the other hand, are on a different stock, & are slightly stiffer in feel.
I think one thing a LOT of people do, as far as flex feel comparisons go, is they'll get a brand new deck & immediately compare it to something they already have. Which is not a valid comparison.
Fresh cards go through a "break-in" process... they wear some (especially initially) & tend to get a little softer over that initial period. Compare a fresh deck to a deck you've used for a few hundred hands of the same cards & you can feel a difference. Comparing a new deck to a used deck of a different brand/version is apples & oranges.
The time it takes for break-in/wear between PVC & Acetate varies as well. They're two different materials with varying properties.
That's why the flex testing/comparison has to be done with brand-new unused cards.
