Like the title says, every time I use my draw tool on certain Coronas the wrapper gets badly cracked.  I keep them at 65rh so they aren't dry. I go.in from the foot and am gentle
 Any suggestions?

 

Can you show an example of the draw tool you're using?  Are you confident in your humidity measurement?

Sounds like the tool is too big for the size of the cigar

I noticed that happen once on a lancero type ring size with the perfectdraw tool but I chalked that up to me not being gentle on the pull and the cigar wasn't well rested.  Typically no problems with that tool.
