But if you want to really fuss over it you could look at many other good options at that website now all for $299 including bindings (and maybe free shipping?):
Atomic Izor 9.7
Fischer AMC 73
Nordica Speedmachine 12.2
All in 170cm should be fine at your size / skill level.
If it were me I'd go with the AMC 73 - even if an RX8 were available this would be just about as much fun doing short turns on groomers but more versatile for just about anything else, and still have that "Fischer feel". YMMV of course.
AMC73 - 118/73/105 (15m) at 170cm
RX8 - 116/66/98 (12m) at 165 cm, don't know if it varies at 170cm.
