The Braggot will be using 6 pounds of Maris Otter 2 Row for the base malt, plus two pounds of British Crystal Malt (.5# I, .5# II, 1# Dark I) all mashed around 158F of 60-90 minutes, plus 12 pounds of honey (type TBD)... I'll be using Wyeast 1728 Scottish Ale yeast. I pick the yeast strain by it's profile and if it can do the job. Right now, I'm using only Wyeast for my beer's, but I've been using Lalvin dry yeast for my meads. I will make a starter for the Braggot, plus use some yeast nutrient, to help things progress along. It's going to be interesting with the merged brew type (part beer, part mead, all goodness)... With the hops I'll be using, I should hit about 25 IBU. By the time it's done, and ready to be consumed, you might barely detect the hops. But, I'm good with that. I'd rather know to increase the hops for the next time, than have to let it age for X more months before it's drinkable (in my opinion). Plus, 25 IBU's is dead center for the style range (0-50)...
I wouldn't say one type (dry or liquid) is better, or worse, than the other. It's more of a personal choice. Plus, how comfortable you are with the strain of yeast.
I do keep a couple of packets of EC-1118 on hand at all times though. Especially when something big is fermenting. Never know when you'll need to use a late addition yeast to finish the job. I might end up needing to add a packet of that to the Braggot before it's done fermenting. Unless I reduce the OG a little, to get the ABV just under 12% (the approximate limit for the 1728 yeast)...
