Hmmm....I find it the same. However, the No-Clean solder (Kestrel 245) DOES flow "thicker". I
find the organic 331 solder to flow almost *too* easily.

Another thing: the 331 solder is picky about temperature. It want 700F, not 710F and DEFINITELY
NOT 750F. If you have a variable temp iron, try cranking the temp LOWER a tad.
