Tyrolia don't have a p18 which is why you might have had issues getting info on them.. they have the peak 18x which is the bomber 8-18 din + race toe.
Good binding for sure, prob about 1200g per half pair due to the metal in them. If you are using a 18din binding, 100grams extra probably won't make the biggest difference to you though
Solid. Think Mojo15 + more metal and DIN
