Why is it that when people give their honest opinions, others feel they are crap.
I guess we not are all entitled to our opinion. As a rebuttal to choosing pump over CO2, it is rather poor. All you voiced was your opinion of our opinions. You may not like our opinions and maybe they could have been voiced better to be more convincing but at least we didn't fill a post with nothing of value. In no way does your post help the OP.
If these are the reasons many do not carry CO2, you should just accept them. Just like I should accept you have a difference of opinion and have found success with CO2. I am happy you have but the OP is asking for our opinion, pro or con, and these are ours.
Also take into consideration that many sit at the keyboard and just run at the mouth typing away and are not always typing the best defense of their opinions.
Both methods work. For me, I am always in a rush and pressed for time. several times I have forgotten to take something with me and had to go back. With the frame pump, if it is on the bike, I cannot forget it. This is also why I carry a spare tube and a patch kit. In case one doesn't work (tube), I can always try to patch the tire or tie a knot in it to get home.
Also, I think frame pumps have been around for a very long time and have worked. When CO2 came out, they did not replace them, they merely added to the options. Says something about pumps.
