They are sort of on my list but I'm concered that they have more of a speed limit than the Heads. Your thoughts?
Here is a review i provided on the 175cm size, I'm 220 Lbs;
"Ski: Fischer 175cm RX-8
Comments: I spent 3 hours on the RX-8 at Stratton, Vermont. This is another great ski with multiple personalities. I enjoyed the edge to edge quickness and the slalom like turn shapes that are very accessible. The ski is very cooperative at all speeds. At 175cm, it will give you long turns with superb stability and then throw down a series of rapid shorties like it was a 165cm Atomic SL:11. At one point I followed a couple of local skiers on racing slalom skis and I was able to duplicate their pencil-line tracks with no problem.
One issue I had with the ski that could be resolved with more experience was the use of both carving and soft edge technique; the ski will accommodate either type of turn and seemed to have no preference. I set the Railflex position at +15mm and this may have limited the skis long turn carving ability a little.
The ski is not tiring or demanding. A great ski for the experienced users looking for a great on-piste ride. My son found the ski very stable in the soft natural snow at Killington. He was using it as a crud-buster with no problem. A great ski for all on-piste conditions."
The general opinion is that the RX8 is easier & more versatile in soft snow than the Supershape. The Supershape is more demanding, but provides more edgegrip and high G-force carving thrills. Neither are built for Super GS race speeds but both are very stable in any recreational situation.
Considering that you have the AC4 for softer days, Pick the Supershape. The 165cm was designed for lighter skiers (at some point). Absolutely take a 170cm, that size is still quick feeling. My 160 lbs buddy uses a 170cm.
Hope that helped.
