The easy way to fix this problem you had is to use a different cut. I use certain cuts for certain smokes. Like almost always, ISOM's are rolled tight so I make sure to always use a guillotine as to open it up almost all the way. Even then I start by only cutting a very thin piece, then more if needed.... Try smoking one of them again, but just use a punch cut/bullet cutter. They have different sizes of bullet cutters too, so look for a smaller one. I use my bullet cut on almost all my non-isom's...
