Disclosure - I am a Reflex dealer, but here is my take.
I have a bad habit of selling my personal Reflex skis so end up skiing on a few other skis. My 'quiver' of skis currently consists of (and note I have tried all these skis for both hands and toes):
Hands:
> Furtif 43" as my go-to ski at the moment
> Quantum 43" my backup
> Stealth 43" which I have a lot less sets on and is currently living with someone else.
Toes:
> 42" D3 Rubber edge - stolen from partner when she wasn't looking.
> 42" Reflex Rubber Edge
My take is as follows:
For hands I love the Furtif. In my eyes it stands well above D3 and Quantum and everyone who rides it loves it. It gets awesome lift, has loads of grip (but this might be as I ordered it with the textured non-glossy base) and is really light. It just feels lively. The stealth gets about the same lift, but feels a little looser to me on the landings (glossy base). Comparing the Quantum and D3 I reckon they are good skis, possibly more forgiving, but feel sluggish and less enjoyable compared to the Reflex's.
For toes, I am getting used to the Reflex rubber edge. Feels like a D3 but with more rocker so it feels like you can rock backwards/forwards a little more on surface turns. Wake tricks it is a little more aggressive into the wake. The furtif is quick rotating, but i would want grooves to get more grip at the front/back to stop rotation. Stealth I admit I havent done toes on yet.
As a side note: Quantum left me without a ski for months when I snapped one - it was off-season apparently. D3 have fixed 2 of my skis including covering the intl shipping back and Reflex had a freshly made custom graphics slalom ski to me within a week after Fedex damaged one.
By the way - have you seen the finish on the Black Glossy Carbon skis Reflex does... its like Carbon Porn...
