TT ... still having trouble with discolouration of my Pro V1x's - beyond a first few holes/first round the stains from grass, sand etc persist - especially around the 'crests' of the concave markings when abraided by short iron play. The ball peforms well but is getting increasingly harder to spot! Can you help? Incidentally NO is the answer to each of the following - are abrasions are caused by hitting trees, flags etc; has there been improvement in colouration with new series; is it not noticed by other players looking for my ball ...there is not a contrast to other brands etc. Sorry, more durable paint?
