Radical toes are, IMO, the standard from which others should be judged. Everything out there seems to be variations of the same thing, with differing spring tension, leverage, and hole patterns, however Dynafit stands alone (to my knowledge) in having side towers. This to me is the best part of building a frankenbinding. Get a heel that suits your purposes and combine it with the best available toes -- at a slight weight penalty over race toes, of course -- for good resistance to lateral jostling that no other toepieces offer.
Wildsnow covers this feature very well, and Lou made a good video of releasing non-side-tower toepeices from lateral jolting. See
