I am quite surprise that some of the relatively later releases like the NS3000, NS5500, ARC5 and Titanium series have already been omitted in this year's catalogue as compared to other earlier releases still listed in it. Probably they want to keep the catalogue slim and show the more recent or more popular models rather than discontinue those not listed.
It is interesting to see that Yonex have changed the ARC009DX,008DX,002,001 paint job, which is similar to the ARC-ZS
I find it nothing short of incredible that the Armortecs are still on the books - the Voltric range is rapidly becoming bloated.
