Here's what I would do with that yeast.
80% Pils (2-row is fine if you don't have pils)
10% wheat malt
7% flaked oats
3% acid malt
Mash @149
OG ~1.055 IBU~35
I wouldn't add any hops until 10mins
Hops @10 to get half your ibus (about 1.5-2 oz)
Hops @ flame out for a 15 min steep for the other half of the ibus (about 1.5-2oz)
Hops when you start chilling and temp just drops below 180F (about 1.5-2oz)
Dry hop 2oz when primary fermentation starts to wind down (day 4-5)
Dry hop 2-3 oz for one week prior to bottle/kegging
Like I said the cascade would work, but I would pair it with another variety or two. From what I see in stock at the places you buy from I would recommend citra, galaxy, amarillo as options to pair with a saison/brett strain combo.
Another way to go at this would be to use polaris @60 to get half your ibus, use the 10 min addition and steep to get the rest. That would save you using some hops, though obviously it won''t be as punchy. Hope this isn't too confusing.
Also, yes that is a fair amount of hops for a single batch. What can I say, I love hop forward styles to slap you in the face
