This thread has been so helpful to me, so far. Thanks, to everyone that contributed.
Ordered from RTS: HS Indian, RY1, and Tab Blend (plus other non HS stuff). Mixed each at ~2.8%, 3.5%, and 5.0% in 60/40 (pg/vg) without nic. and steeped for 7 days (sampled) then steeped another 7 days (sampled again).
I sampled on a 510 bridgeless atty (1.8ohms at 3.7v = ~7.6w)
My background for comparison: Smoker for 25 plus years (PAD), quit last halloween. I prefer tobacco flavors with minimal extras like vanilla, nutty, etc. though I do welcome them if they are subtle enough.
My opinion of these flavors: At 5% the flavors are quite strong to me. I feel like I'm tasting a nutty component with the RY1. The Tab blend and Indian I can't do at 5% and only barely tolerable at 2.8% so I took them down to ~2.2%. Not that the taste is bad, mind you. Rather, the taste is just so strong.
Waiting another week for steep then will sample again, but overall I'm not thrilled about these particular flavors. But what's more important is how well done those flavors are! I can tell I just need to keep playing around until I find figure it out. I'm looking forward to trying others HS flavors. I'm especially enthusiastic about delving into the realm of fruity and other flavors, having only been trying tobaccos until now.
Side note: I've heard more than one person describe the HS Indian as comparable to FA Shade. I currently vape FA shade and did not taste any resemblance at all. Was kinda' hoping I'd like the Indian, though. Biggest surprise was how I didn't care for the RY1. I was really expecting to love it as much as everyone else apparently does. Maybe a different percentage? I can't see this tasting anything else but stronger than it is at 5%, for example, so I'm hesitant to even bother.
I'll report back when I sample them at ~2.2%.
