Yes, I like strong tobaccos as well and mix HG at 8%. HG Desert Ship is my only exception and I mix at 6%. Thoroughly enjoyed some DE tonight and was thinking to switch my #1 recommendation. Since the RY4 is out and you already have the red, go for it -- you won't be disappointed.
HG is my overall preference for tobaccos as well. FA's strike me as more "tobacco-like" than tobaccos. And seems I'm finding too many Inawera tobaccos with that "buttery" flavor that I avoid. Meanwhile my only HG suspect is their Pipe tobacco.
Anyway consider also giving the DE tobacco a try and post your thoughts.
I find my sweet spot with all hangsen tobaccos at 7%.
