Mini Pump with CO2 Inflator
Has anyone tried any of the hybrid tire pumps that combine a mini-pump with a CO2 inflator? I've been looking at the Topeak Hybrid Rocket HP pump and would appreciate any comments.

I quit using CO2 due to the expense. When I started riding recumbents that had larger volume tires it was taking 2 16 gram carts to fill a tire and that exceeded my gag point. When I was using CO2, by the way, I expirated the tubes into shape so I didn't need any dinky little pump. The trick with CO2, by the way, is to be sure first that your tire is seated properly. Otherwise you risk blowing out your new inner tube and also losing your CO2. The technical term for that is "screwed".
Now I use pumps. I like a big pump that takes a lot fewer strokes. My current favorite is a Topeak Morph that, though ugly, is still compact enough to fit into one of my recumbent bags so I don't care. I HATE smaller pumps.
If I was to combine any pump with CO2 I would want a high volume low pressure pump to partially inflate my inner tube before installation and to check that the tire was seating properly. In this case, dinky would be OK. Then I'd use CO2 to top it up to operating pressure.

Lezyne has a braided bose to replace the standard "rubber" hose for their Road Drive pumps which threads directly onto a CO2 cartridge, the nice fhing about that being that the hose stows inside the pump as does the standard hose, so the only extra thing to make room for is the gas cartridge.
The Road Drive is a really efficient pump up to about 28-30c in the Medium size. Beyond :0c, I'd suggest the large size, unless the gas capability is an effort to minimize pump size, in which case I'd recommend going with the smaller "M" and accepting the extra strokes

I want the gas capability because I have neither the desire nor the endurance (I'm a 70 year-old female) to squat by the side of the road in 100+ degree temperatures and pump up a tire by hand. I want the pump capability to seat a tube and also as a fall-back if I run out of CO2.
