An MSR SuperFly on a Rando 360 cartridge. Highly unstable, but it works. If it tipped over while lit, the stove would probably have a serious flare up which would be very dangerous.
An MSR SuperFly on a Coleman PowerMax canister.
You can clamp on, but you can't get the gas to flow. The PowerMax canister's connector is too wide to fit into the connector of the SuperFly. If it did work, this would be extremely dangerous because the PowerMax canister is designed for *liquid* feed.
