For my votives I have been using primarily the 740 some 745 but I do not dye my soy candles. As far as using the 770 in the tin, what is the diameter of the tin? I have found with my 8oz jj that I have hang up on the first burn but it is usually gone the 2nd burn and by the 3rd burn no hangup. I tend to wick to big initially and I have to get over that. I find that if I wick to large I get big 'shrooms.
