bubble bags

so going to make bubble hash, and im geting to the point where i need to get the bags. my delama is whats the difference between geting a 3 bag or 5 bag? whats better to get? they got em on ebay for 30 bucks and 50 bucks. let me know asap payroll is tonight. thanks

I bought the 3 bag system.. I just figured I didn't need 4 grades of hash for me to smoke... works great too BTW... smoked BT's for a week.
