RIS Recipe Critique

[SomeN00b]

Hello all, long time lurker first time poster. After making several of other folk's RIS recipes, I've decided to try my hand at designing one. I expect, given my previous experiences with big beers, this to end up with an FG of 1.025 - 1.030, though I have never used WLP090 on a beer of this size. Any feedback is appreciated!

Haven't made an RIS before but that seems like an awful lot of roasted malts even for an RIS. Probably don't need so many different kinds of malt either.

It's a 12 gallon batch. It's not too much roasted grain at all.

Looks good OP. Might want to toss some flaked oats/barley in there for extra mouthfeel.

Thanks for the feedback guys! Maple, I haven't used flaked wheat before, but I was hoping the flaked wheat would help with mouthfeel in addition to head retention. Is that not the case or would flaked oats/barley just help more?
