did anyone noticed a difference in diameter for the 8mm black pole hose that Alex is selling ?i ordered one recently and it's rather thinner than the old one which makes a big difference .i mean i can't fit the flow control anymore as it's thinner and comes lose.or maybe they put the 6mm tubing instead of the 8mm but checked the packing and on that foil that was wrapped it's says MH5/8BLK30M.anyway i might just give them a call in the morning.i was just wondering if anyone noticed any difference.thanks
