Reply to Traktor Timecode vinyl is more slippery on one side?

Hi guys,

so i've been spinning on side b of my traktor timecode vinyl mk2 (black) i.e. side a with the traktor logo is down.

and decided to try the option of loading the next track when the tc vinyl is flipped.

Side a: 12min (with traktor logo only)
Side b: 17min

i've noticed that when side a is up (side b is down facing the platter) it is MUCH more slippery, huge difference. whereas when side b is up (side a, is down facing the platter) it is less slippery.

Is this normal ? and how will it affect my mixing/scratching?

on the same topic, where do u guys mark the traktor vinyl sticker on ur tc vinyl? the instructions are to place so that it points to the little marking "dot" on the vinyl. but i assume where i place it dosent matter?

thanks!
