Myself being a bit of an EJ, I bought a couple of new colour rubbers and 1 red sheet, in the Black Friday sale at TT11, 30% off so okay deal !!
last night I played with a blue Donic Bluestorm Z2, it played very nicely!! haven't used this rubber before so can't comment on whether it plays as per a red or black sheet, but there maybe a myth involving how colour effects a rubbers characteristics anyway.
The question of different colours is quite interesting,
I've heard that statistically Green coloured cars are more likely to be involved in accidents!!
Red is a strong colour regarding winning, that possibly more matches or games are won by teams wearing Red, Tiger woods always seems to wear Red on the final 4th round of golf tournaments !! Other colours are seen as calming or cold, warm etc
it will also be interesting to see how things pan out with the Pro's, if they start using the new different colours, with stats recorded as they are these days, will there be an increase in wins with a certain colour??
if you watch the ITTF video on how they chose the new colours, there is one point made that a couple of colours were seen as 'irritating' by the opposing player, these colours were then removed from the shortlist.
