If I was you id stick with what you have been using maybe add a little wing n slight softer, other than that I wouldn't change anything now and if needed get in for wet tires.
Also the wets tend to last ok in slight drying conditions to even when they display crazy temps etc, btw I will be racing tonight still dayshift and home early today
I did my wet setup test and needed to add more wings, make the aerobalance more.. well, balanced as i had a bit oversteering before (12/12 to 14/17) loosing just a couple km/h at the end of Kemmel straight. Also i took negative toe-in away at the rear.
