Tuning for BD Aspects?

I've just started using Black Diamond Aspects for backcountry.  These are pretty amazing skis, featherlight with Dynafits.  Here's the story.

 

The Aspects are 186 cm, 132/90/119 with 20m radius.  I'm 6'2" 200 lbs, skiing in new england - everything from powder to ice, crud, crust and hardpack.  I put on 1deg base and 2deg edge angles and detuned about 8" back from the tip and 5" from the tail..  Nowhere near enough detune!  Insanely hooky, catchy, complete PITA. 

 

Then I detuned about a foot or 14" from the tips and 10" from the tails.  The Aspect's tip rise is pretty shallow.  Transformation!  Easiest turning skis ever.  Sometimes too easy in fact, and that's the issue.  The Aspects are incredibly carvy skis, they just want to carve turns.  The slightest knee angulation and they turn, makes instantaneous short radius carve turns on hardpack (or even crust) effortless.  It's like skiing on rails, and that's the issue.  It's really, really hard to skid or aggressively jam the downhill ski, as when doing a kind of hop turn on steep hardpack.  Edges are uncomfortably catchy, scary sometimes.  Powder or softer snow is fine.

 

FWIW, I also ski BD Verdicts (180cm, 134/102/120, r=26m) and Havocs (185cm, 123/88/115, r=22.5m).  They're tuned the same (except shorter detune) and I don't have this problem.  I have no idea about respective stiffnesses, rocker or any of that. 

I'm something of an old school skier, learned to ski on straight skis but I ski anything.  Can edges just be too sharp?  Too much edge angle? Seems like a ski should be able to skid turns when appropriate and not just be forced to carve.  Or maybe I just suck - though sometimes I still deliver regular beat downs to punks on my antique 205 cm Rossi ST Comps just to make a point ;-).  Any thoughts?

Nobody?  Can't tell if the question is too exotic or too stupid...............  I'll try on TGR.

No - or at least no more than the havoc's or Verdicts.  I guess that really means "I don't think so."  They were all tuned the same way within days of each other.  BTW, skied 'em in a kind of half-packed powder/crud yesterday, they were beautiful.  It's the hard snow that's annoying.

 

anything is worth messing with for somebody that likes to mess.

Thanks, interesting. Is your thought along the lines of [2deg base], [0 deg side] on tips and tails? Then tips and tails would have less bite? Maybe 14" from the tips and 10" from the tails? That's about as far as my detune went. Would a gummi stone take care of the edge burr (if any)? I'm new to all this fancy tuneup stuff.

 

Nice diagram.  I'll give it a shot.  BTW, I got my binding mounting stuff from you guys.

 

 

 

I dunno.  I find it hard to find the perfectly neutral, natural angle.  I've played with boot cuff angulation in the past, but I really can't tell much difference and end up at a neutral setting.  Playing with canting or wedges is way to fiddley for my taste.  Until now I've always been in the "it's the skier, not the skis" camp and pretty intolerant of complaints like the one I'm now having.  And my other ski/boot combos all work fine so I think it's something specific to these skis.  Or maybe they DON'T work fine but I just don't know it cause I'm subconsciously compensating!  At this point it all gets too much for me.........................
