Well, I can tell you that I haven't been able to completely confirm that the faintness of the strips means anything at all. ( Ive been trying.) There are differing views on that, read my thread. So I wouldn't put too much weight on how dark your lines are from test to test. Let me tell you this also, people do Not like it when others ask if they are going to pass yes or no. Its your body, you know more about yourself than anyone else, we don't know your metabolism and therefore anyone who actually doesn't want to mislead you will Not answer that question with a yes or no. If you truly are getting a gc test, not sure if what you wrote necessarily means that its automatically sent to the gas test as im not up on drug test notation, it will be alot more sensitive as you seem to already know. Passing your home test with no extraneous means is a GOOD first step. Remember a few things, drinking lots of water days before the test does Not help you rid yourself of thc metabolites faster, lots of posts containing that. Exercising is probably the best thing you can do in your situation, get into some good cardiovascular workouts Everyday for a while if you have time. Doing that and increasing your calorie intake daily will up your metabolism and is the best way to flush your system. Do not work out a few days before the test, be lethargic without the smoke and make sure you keep your vits up. 5 weeks of quitting is an aweful long time (better man than me) and I'd say you have a good chance to pass either way if you keep a good regimin (spell check) and follow N2's advice slightly. (no first piss of the day, mid stream, drink, take vits, etc.) No need really to heavily dilute and risk a diluted result if your already pissing clean. Hope that helps, and for reference Never listen to anyone that tells you you WIll pass for sure. They're usually the same people who say that sure gel lines the inside of your stomach and makes cleans.
