Stout planned for Fathers Day

Ok so I'm trying to figure an oatmeal stout recipe, here's what I have so far...

4.5# 2-row
1.5# Munich
.75# Oats
.5# Chocolate
.5# Roasted Barley

1oz Cascade (60 min)
.5oz Tettnag (60 min)

S-04 yeast

60 min boil

boil size 3.25 gal
batch size 5 gal topped up

Will the roasted barley and chocolate be too potent or will it be fine?

thanks for the help

 

I'm no expert just got into brewing but I think that would be fine. But don't trust my word on it

 

I thought it would be fine. I was at the lhbs and just grabbed a bunch off the top of my head, want to use my leftovers for a 3% session beer.

 

Well usually don't you use a pound of one of them for a stout? So I think .5 of each should be fine.
