Pumpkin Ale advice

[BMacD]

Hey guys.
I just purchased "The Brewhouse Pumpkin Ale"
http://www.rjscraftwinemaking.com/product/Pumpkin-Ale?pageID=75874baf-db19-599f-4eab-388fa78e78f4&sortBy=ProductTitle&maxRows=10&

I need some advice on the yeast to use. The kit comes with a 15g Coopers yeast. I also have a pack of Safale S-04, Safbrew S-33, and a washed mason jar of Safale US-05. This is info regarding the kit

Bitterness: 22 IBU
Malts: Pale Malt, Carastan malt
OG: 1.046 -1.047
Hops: Northern Brewer and East Kent Goldings
Colour: Straw, golden
Serve: 7˚C / 45˚F

I'd debating between the S-04 or US-05.

Also, if I was to used the washed US-05, could I mix up the brewhouse kit and use 500ml to 1L of that to create a starter for a 24 hour period to get the yeast active again (about 2 months washed) and pitch without harming the wort?

Thanks in advance!

Here's an idea, split the batch after the boil and use 04 in one and 05 in the other. You'll get a chance to taste the difference between the yeasts. Either will work well.
