Most if not all Metrons were only concave in the center of the tip and tail. This had no negative effect on sthe ski's performance since all you need is a flat base about 10-mm in from each edge. You should never try to grind a ski like this flat. You will just dramatically shorten the life of the ski or ruin the ski completely.
I would honestly put my money on concave base (edge high) or simply a "flat" base bevel being the route of your trouble.
Seldom do these skis have too little base bevel, if anything usually too much and if they have been skied a bunch unless recently stoneground to flat with no base bevel, this is probably not what the problem is. Could be a hanging burr though.
Going up to a 3-degree will just mean your edges dull quicker:
The paragraph below was written by SKiMD Mike DeSantis, pay special attention to the underlined portion!
SkiMD produces all side edge angles at 3.0 degrees. More factories are realizing that it’s worth the hassle to recalibrate side edge machinery to this parameter. Why? Because shaped skis are able to achieve higher tip angles with greater leverage than straight skis. As a result, skis with less than 3 degrees of side edge will have a tendency to chatter, as the upper portion of edge interfaces with the skiing surface and “boots out” the lower portion.
Never let anyone try to convince you that this is too radical, or that it gets duller quicker. No information exists to support that theory. The difference in material removal between a 2 or 3 degree side edge angle is truly minimal over a side edge height of 2-2.5 millimeters. However, the difference in performance when asking your skis to do what you want is profound.

While at Volkl, Mike was overwhelmed with the negative feedback on the company website from consumers in regards to their first “shop stonegrind.” The retail effort back then and now continue to be apathetic regarding the proper restoration and installation of tuning parameters. Realizing the need for someone in the ski service industry who could consistently deliver the proper finish to shaped skis and snowboards, is what prompted Mike to leave Volkl and develop the SkiMD Refinishing System.
Mike’s extensive background combined with 43 years in the sport of skiing, are instrumental to his success:factory level service. 20 years of continual development has created an ideal refinishing system that works for everyone.

Mike created his own proprietary finishes for top athletes such as Hilary Lindh, the 97’ DH World Champion. Kate Pace, the 93’ DH World Champion. Katja Seizinger, the overall World Cup women’s downhill winner many seasons over. Other athletes include Picabo Street, Kristina Koznick, Heidi Voelker, and former U.S. Snowboarding Team athlete Rosy Fletcher, Olympic Bronze medalist. Working in tandem with Volkl Germany, allowed Mike access to some of the very best factory technicians in the world. Combined with deep factory knowledge of ski design and construction, the foundation was built to create a system that has such a broad level of success. This is what truly differentiates SkiMD from all the rest.
