In M K1 ? Big I would say. Basically you have no real competition for the last available quota, all strong nations and good paddlers from smaller canoe slalom countries are already qualified.
For me, your main opponents will be apart the 2 countries with naturalized slovak paddlers (Samuel Stanovsky) and (Marcel Potočný) mainly but the one I would more affraid is Matthieu Doby. however as I said honnestly Poland with 3 decent paddlers should win this quota on paper quite easily. but again we know that in this sport you always have to count on that randomness factor in a single race, one silly mistake and everything can happen...
I would be more worried about the W C1 quota for you, Here I am afraid the task may be too hard for your girl(s) facing 3 paddlers from France, Slovenia (both still can be qualified directly via reallocations - HOPEFULLY) and Slovakia your chances are basically inexistant
