After doing some research, I decided to forego the co2 route in exchange for the blackburn airstik sl. The airchuck with a 16 ounce canister weighed 84 ounces on the scale at work (accurate). The blackburned weighed 59 ounces. On three seperate fillings, it took on average 3 minutes to achieve 80psi which wasn't too hard to do. So the blackburn weighed 25 ounces less, has unlimited fillings and cost the same so can't justify going the co2 route. It did save me 71 grams over my previous pump Thanks for all the input.
