You might have some trouble finding 2 sets of solid bindings for under 200. Usually 1 set is around 200. ANd both of those skis are NOT 100mm wide. Both skis are under 85 underfoot, so look for something that is much closer to the actual width of the skis.
If i were to suggest a solid binding, look at Tyrolia attack 13s for a solid binding, but those are around 200 for 1 set.
