That's a lot of 2-row for a 5 gallon batch, if that's what you're making. High mash temp too. I'd rather use some carapils or wheat and mash lower, but it's up to you. You definitely could mash lower and still having juicy hop sweetness you're striving for by utilizing the bulk of your Simcoe and Citra for a post-boil aroma steep as well as a dryhop. 1 oz. per gallon of beer ratio for the dryhop. And slightly less for the post-boil addition.
Citra doesn't have a dank funk. It's a tropical hop, reminiscent of lychee fruit with a backnote of grapefruit. It's very juicy and fruity. Simcoe has some tropical notes that serve as a backnote to its piney musk. Summit is primarily tangerine with some dank resin in there that some say is akin to onion. I would bitter with Summit, add another mid charge of Summit or Simcoe, and then pound it out at post-boil and dryhop. Maybe add a 10 minute addition in there if you have hops to spare and want to use them, but this isn't exactly necessary. Your IBUs should be high enough without 20-15-10-5 minute additions. And the character given by the loads of Simcoe and Citra added at 0 & DH will be quite substantial.
