Whistlepig to me is just a massive massive rye with a lot of richness to it. I"d consider it a bourbon drinkers Rye. But I do agree with what your saying about the LDI juice being a high note component for blending. It doesn't need the weight because it wasn't originally intended to "go it alone". I'm sure glad some folks have put it out though, because it's so interesting and tasty.
As for High West, to my knowledge, the LDI juice they used was the 2 year for Double Rye! (younger than Bulleit and in line with Redemption) and the 6 year old for Rendezvous. I am not aware of the other older rye's for their blends being LDI products. Could be wrong, but I'm pretty sure it's only the young ryes that are from LDI.
Reports I've seen indicate this Bulleit Rye being between 4-7 years of age.
