I think this is a good idea. After years (decades) of bouncing around I've finally decided on about 8 styles that I will alternate making, and keep tweaking the recipes until I think they have become great. So far it's been a good idea, I don't get tired of them and I really start to learn how small changes affect things.
I'm very happy with the result! Taste is malty, chocolaty, a bit of roast and a kind of cherry/molasses fruity taste. The beer has a medium body but is still refreshing.
The bottle needs a bit more time to have a proper co2/head but generally it is a HUGE improvement compared to my first stout.
I'll brew it again with 2 modifications (next version ):
1. I don't think the oatmeal made a lot of difference. I think I will only use flaked barley next time.
2. I think the chocolate and roasted barley could be a bit more balanced. So I will lower a bit the chocolate malt and raise the roasted barley.
Apart from that, it was my first time using Irish Ale Yeast and surely not the last.
I need to work on a tasty red ale recipe and this yeast seems to be a good candidate
