My first post on BW.C

I'm building a light weight kit and looking at a couple of options for light, quick/ easy convenience gas canister stoves and to cut the weigh. Use would be Oz bush maybe snow, maybe NZ mountaineering (v low priority). Has anyone had any experience with the following:
Snow Peak GigaPower (auto ignition)
Coleman F1/Power boost.
Optimus Crux Lite
Ive read few articles /reviews re wt vs fuel vs cost etc, so not looking for info on liquid stoves - got that covered already.
Im looking for something that is light, works well with good simmer control (all the above have simmer). I'm also inclined towards the 'burner on the canister style', as I think this is lighter overall, and just as good. Also provides some canister warming in cold conditions.
I like the idea of having a piezo ignition in case I grab and go and forget lighter/ matches, even though in the pack I usually have both. I did look at a Jetboil, but as I already have kettle/ pots, so didnt want to pay the money for what is a good stove, but not what I need. One thing I am mindful about is that these sort of stoves suffer in the wind, and would plan on a wind shield of Al flashing.
For a pack I have been suggested the GoLite Pinnacle. I saw another thread on light packs, and read with interest. Im not in Syd so can check out Kenny's (?) pack choice, and Im not convinced a $50 pack will last very well. TWT. Does anyone know if the Pinnacle has frame, I do not think it has. Any comments on the GoLite Quest as this is more along the lines of what I favour - it has a frame. Any other equivalent options I should look at? I am also mindful that at times I might carry towards 20kg. but hoping to get away from that with the new set up. I am not aware of anywhere in Oz that sells these, but given the $ is good against the USD, its a good time to buy.
Tents, Tarptent Contrail ~780g, good reviews and advice from users.
Thoughts & experiences on any of the above, especially the stoves ??
