I can smoke the first half of the bowl down just fine with an occasional relight. When I get to that half-way point, the thing won't stay lit for anything. I have tried going in with a pin to open the tobacco slightly as well as the spoon on my czech tool to loosen everything up. It seems the bottom is packed pretty tight even though I feel like I've backed off significantly on initial packing and take care when tamping during the smoke. Any ideas about how to solve my dilemma? Tired of wasting the last half or getting so frustrated I lose the relaxation from the first half.
