hello, after an attempt to CTB last month my family is on high alert, meaning im not able to act, when i move out late next month, ill be proceeding with my plan, however ill be living in student accommodation, so i cant order N2 directly to my building as its a prohibited item, due to this, ill have to order it to a local pick up point
my problem is that the only nitrogen bottles ive seen on ebay are 2L (28 mins gas flow) or 9L (82 minutes) the 9L bottle i found comes with a regulator and tubing, but the only issue is that it weighs 15kg and is 82cm, so id have trouble transporting it, ive not got a car, so id have to get an uber from the pick up point, and carry it up some stairs to get to my room, would you recommend attempting to carry the 15kg bottle (im around 41kg) or just attempting to CTB with the 2L bottle? im not able to order gas directly from the supplier as i have no car and I doubt they would hand it over if i told them i was transporting it in an uber, also the 9L bottle is 82cm so the driver might have some questions but i could fit the 2L bottle in my bag safely
was thinking of ordering 2 bottles of the 2L nitrogen bottles and only setting off the second tank once i put the eb over my head, but im concerned that will produce a surplus of gas and that the bag could potentially explode
basically, what would you do in my situation? how risky is it to deviate from the recommended 40 mins of gas flow?
maybe i should clarify that the 2L tank is at 200 bar so it would be 420l at atmospheric pressure, and the 9L tank is 137 bar and would produce 1233 litres of gas at atmospheric pressure
