Once again, the industry is not the best friend of either the consumer or the retailer. As bad as it was with Rottefella's cheesy NNN system duking it out with Salomon's more solidly made and better supported SNS Profil and Pilot systems, things got worse when Rottefella convinced its manufacturing allies to adopt the NIS plate that only accepts an NNN binding. While a mounting method that requires no jig and no drilling eliminates most of the problems that made NNN so failure-prone, it also eliminates consumer choice in an obvious move to monopolize the market.
To make matters worse, Fischer and Rossignol decided to stab Rottefella in the back and introduce their own plate, the IFP, that excludes Rottefella bindings and cannot be drilled to mount a Salomon binding on top of it at all. With many -- perhaps most -- skis coming with either a Sin plate (NIS) or the even more heinous IFP plate, consumer choice gets funneled down to just what a couple of manufacturers are willing to provide. These decisions are made by accountants, not by skiers.
Fortunately, the IFP binding takes a regular NNN boot. We haven't quite returned to the System Wars of the 1980s.
Salomon offers their skis pre-drilled to accept any of their own bindings. They also sell an NNN-compatible boot and binding system for skis without a plate. As always, Salomon's version is much better made than anything produced by Rottefella's manufacturing partners. This keeps a shred of choice left in the marketplace for consumers who want or need to mix and match.
But wait, there's more.
If you have chosen a moderately heavy ski, perhaps with a metal edge, you will have better control with a beefier boot and binding. The only heavy system binding widely available is Rottefella's NNN-BC. You can get boots for NNN-BC ranging from something slightly heavier than a regular touring boot up to some gnarly models with buckles and external cuffs designed to drive and control the new generation of shorter, wider off-track skis. This is still well short of the state of the art in downhill-oriented backcountry skis. Telemark equipment has reinvented the alpine ski, making the free heel aspect of the turn completely irrelevant.
You can still find boots for heavy 75mm bindings. These were generically referred to as three-pin, even though some models had no pins at all. Some cable bindings used a slide-in toe piece with a fixed bail. If you really plan to take touring skis more than a couple of miles from where you parked your car, use 75mm bindings and boots. They're a proven workhorse. If you prefer touring in semi-refined environments like snowmobile trails, then the NNN-BC system will allow for somewhat more fluid striding -- at least as fluid as you'll get with a chunky BC boot sole.
It gets tricky on skis that barely reach the threshold of heavy, such as the Fischer Spider 62. Available either as a flat top or with a SIN plate, Spiders are easily skinny enough to use in a set track at a touring center. But the metal edge on the Spiders makes them a trifle heavy for the cheapest and lightest touring boots and bindings. If you don't push the skis very hard, you might not notice any control problems, but then what was the point of buying a ski with a metal edge? When you jam on the emergency brake, you want it to dig in. Salomon's two-bar Pilot binding gives a lighter boot more lateral control than a basic single-bar binding would. If you're looking at metal edge skis 62 to 70mm wide, choose the Pilot binding or a BC system binding. If nothing else, make sure you get a manual binding rather than an automatic step-in if you go with light touring boots on a ski like that.
It's disheartening to see the suppliers of the cross-country ski industry fighting over market share like a couple of street dogs scrapping over a half-eaten carcass in an alley. Economic competition does not necessarily favor a better product, only a better marketed product. I guess they all control a ski better than a leather strap across the toe of an elkhide mukluk. In the modern era, it's not about getting large numbers of people to enjoy the physical and emotional benefits of an activity. It's about getting the largest number possible to spend the largest amount of money on it.
