I have been thinking about retiring the Coleman 442, little smaller than your Coleman isn't it?
That Primus Omnifuel looks very interesting.
Would have to see some heat output comparisons first vs the Colemans,my very beat up 442 sure puts out the heat. Fast on the coffee in the morning.
I already have the 1.5L bottle for a Primus.Does come in handy sometimes when it is full and quickly accessible from the saddlebags.....
