>Can anyone tell me the pro’s and con’s of both systems.
In general open-top stoves can be lit by touching a flame to the inside of the stove, and they are generally a bit harder to blow out. Pressurized stoves usually require priming to get started, and the priming flame can usually be blown out easily. (A wick may be a bit harder to blow out; don’t know.)
I find open-top stoves to burn a bit more yellow than pressurized stoves (less efficient?). One compromise is an open-top stove on which you set your pot (a side-burner), thus converting it to somewhat more of a pressurized design. However, I think side-burners don’t heat as well (at least the designs I’ve tested).
I still like my Pepsi-can stove, but the Penny stove is a good pressurized stove that is easily made. The Cobra is also easy to make, especially from Red Bull cans (since it’s pressurized, diameter isn’t as important).

I recommend making both of these and comparing them to your Pepsi-can stove. Try lighting the stoves in the wind.
Tinny at Mini Bull Designs has fiberglass wick for sale.

I was surprised at the amount of heat that Tinny’s stoves put out (I have an ION precursor). Concentrating the flame on the screw makes my MBD alcohol stove hiss like a canister stove!
