I tried HTP 105s in 3 jars...with my jars, I usually go up a size from what I'd try in an 8oz reg jj...(to give perspective). I like the way the htps burned better than the ecos...I don't know what it is that I don't like about the ecos but it seems like no matter what I try...I never get a good burn. With the HTPs, though, I think it was burning too hot and by the end of the burn, they were flame throwers (but I also may not have trimmed the wick as much as I should have so still need to test). I'd try a 104 but those sometimes burn hotter than a 105! All three had wonderful hot throws! I had the GL Vanilla Lavender in my bedroom and it was coming down the hall and into the living room - loving that scent! Jen
