This is the first time I have heard of the Triton water filters from Prismedical Corp. They have an interesting set up. The only disadvantage I see in their set up is that you have a wait time of 15-30 minutes for the viruses. Some people have said in this thread that they have a virul module but I don't see that on their website. They have a virul solution with the wait time.
I think you could use the Triton MC carbon module (under 3 oz.) with a Seychelle inline filter advanced (.3 lbs). This set up would appear to have all the advantages of the Triton M3 multipurpose plus virul elimination without the wait time. The Seychelle inline filter advanced supposedly has a iodinated resin component in it so you wouldn't need that component from the Triton M3 Multipurpose. I don't know what the flow rate of this set up would be. The Seychelle inline filter advanced may already have activated carbon in it in which case you wouldn't even need the Triton MC carbon module. I cannot gather from the Seychelle website weather or not their inline filter advanced has activated carbon in it. Though it does say it is suppose to improve the aesthetics of the water, i.e., taste, odor, silt, etc. and under their FAQ page their is a question about activated carbon filters which I presume is about their own filters.
You could also probably use the Triton MC carbon module, the Triton resin module ( presuming the resin module has a hose link on the output end, the MC has an input and output hose end) with a Sawyer inline purifier. This would seem to be a complete lightweight purification system as well.
The Seychelle inline filter advanced may be a complete purification system on its own which they propose it is ("The only personal water filtration system capable of up to 99.99% reduction in all four areas of contamination!
Aesthetic, Microbiological,Chemical,Dissolved Solids").
It has the resin component, possibly the carbon component (I'll have to give them a call about this), and the filter component to remove bacteria, protozoa, and viruses. Anybody have experience with the Seychelle inline filter advanced? The flow rate?
