Just a comment that might influence your decision.
The Ti-Tri is very flexible in that it gives you multiple fuel options, but when using it as a wood burner leaves you a very dirty, soot covered mess when you have to break it down and to put it in your gear.
My friend, Jeremy, took it with us on the JMT and it did come in very handy when we found that we could not buy esbit fuel on the trail. Burning wood one night helped conserve what esbit tabs we had left.
However,the soot was all over the cone and left his hands a mess after breaking it down.
Having a plastic back or placing in the included caddy would be a must to avoid getting soot all over your gear in your pack.
In my case, I do have the Bushbuddy and find that though limited to burning wood....it is a cleaner option for me.
I have a feeling that the Bushcooker Lt will be the same vs. the Ti-Tri.
I am sure you know this, but the Bushcooker is a specialized product as as such is likely to be a better wood burner than the Ti-Tri.
The option for you going with the Ti-Tri is your deciding if you value the flexibility to use different fuels on your trips vs. only being limited to wood. The negative with the Ti-Tri being less efficient and messy/dirty when burning wood.
Again, I know that you can rig the Bushcooker to burn alcohol, but I would you actually bring an alcohol stove or esbit with you "just in case"???
I think the choice for you is going to reflect your philosophy and approach to UL.
Highly specialized that does one thing really well (Bushcooker Lt) or having/owning one system that CAN cover all of the possibilities...though more specialized for Esbit & Alcohol.
Anyway, hope this helps.
