I know it is late response, but i just purchased a Ti sumo and used it for the first time. My experience was also that it is a piece of garbage.
Pre-trip test showed that the burner wobbled a fair bit in the shitty plastic retaining system, so much so that it looked like it overbalance unless on dead flat ground.
First melt of snow on trip, burner on gently until we had some water then turned up. Result was melted plastic support on the burner melted, and much of the flux ring seperated from the cup and more or less combusted.
After that it still worked, but couldnt get the heat into the cup.
Our group already use a PCS and Helios Guide system with great success.
Has anyone had any success approaching Jetboil about the weight saving and cost saving design??
Previous jetboils have seemed bomber.
