Any table is affected.If a table plays that bad from just humidity. The pile of shit needs to be thrown in the trash. Diamond are so shit when temp etc. Are thrown at them.
Particularly modern high reacting cushions like the Artemis cushions. Pair that with 2 week old Simonis worsted cloth stretched tight...it can play like lightning.
Good players adjust....absent these type of conditions a Diamond plays like a Diamond. I owned 8 in my pool hall and have another one now in my.garage with no heat. They take plays like all the others...until it gets like 10 degrees and it slows those cushions.
I have played in high humidity before and the springy cushions are real....and once in a while because the cloth on the rails is too tight I have seen them come off quick.
