I'd be interested to try this as an all extract recipe, would this work? (I havent done an all extract before, so excuse my newbie status if this isnt right

)
1 tin liquid malt extract
1kg dried light malt
500g crystal grain
50g chocolate grain
20 g Northern Brewer (Pellets, 7.4 AA%, 60 mins)
18 g Amarillo (Pellets, 8.5 AA%, 30 mins)
10 g Cascade (Pellets, 6.3 AA%, 15 mins)
10 g Amarillo (Pellets, 8.5 AA%, 15 mins)
10 g Cascade (Pellets, 6.3 AA%, 2 mins)
Wyeast 1056
Any suggested changes to this?
