the last knuckle/? which one is that haha, one close to the tip? assuming it is

1. would be nice and high cause i use a waterfall which gets you really high imo. so probly around a 5. nice and high for about hour then it slowly tapers off and at the 2 hour mark is when i find myself wanting to smoke again.
2. waterfall bong
3. 3 always real good shit
4. few times a day, a lot more if im with my friends, the occasional day or 2 that i go without

I use the waterfall cause im broke i really dont have much money to spend on weed and it conserves good but honestly i would smoke a lot more weed if had money theres no such thing as too much weed imo
