So for AG#13 i was planning on making a duvel type clone this week , however with the recent weather I think id prefer something a little less strong and more thirst quenching

I have ~5kg of lager malt, but im happy to use pale malt instead and I also have 100g saaz.
The only yeasts I have on hand are US-05 and S04 so im not aiming for a true lager.
I'd like to aim for an OG of ~1.035-1.040, do people think a brew of this strength will be ok with just pale malt and saaz?
What sort of IBU should I be aiming for?
This will only be the second recipe I have attempted that wasnt out of a book so go easy on me

Cheers guys,
Kane
