Yes, looks like the AS511SB may be the way to go, or a Bitex BX301F from Bikehubstore, the latter being slightly heavier but with bigger bearings (the Bikehubstore site is wrong - it has 2x 6900 bearings not 4x 688). The AS511SB has a better bracing angle though. Hmmmm...
RS10 (what he wrote) is straight pull but 16H, RS010 (what he linked to) is 20H but J-bend :-)
It seems unduly hard to get the Novatec AS511SB without having to buy the matching rear, but this Czech shop lists the front only for ~£45
