Amish harvest and buttercream revisited

[RWV]

My fav Amish harvest that threw like crazy was originally from Tennessee candle supplies.  I know I’ve read good things about Peak’s but am afraid to go that route right now.  Keystone is out of stock on the 16 ounce size, so I was wondering if FB Amish harvest is like Peak’s and if it’s as strong.  Also, is RE’s Celtic Moonspice as good as Peak’s in the throw department for those of you that have tried both.  Years ago, I tested the Celtic Moonspice and it smelled similar to the one I had from TCS, but don’t remember how well it threw.  Any other Amish Harvest scents y’all can recommend from other suppliers.

Secondly, who do you think has the best and truest buttercream?  I have tried many—Daystar’s and Bluegrass (now at RE) seemed to be the most authentic but I never could get Daystar’s to throw well in my parasoy blend and the one from Bluegrass/RE was a real wick clogger.
