As sthughes said, you are carrying a tent for one of two reasons. Either you will sleep in the tent in preference to sharing a crowded hut (if necessary) - my choice - or you will use the tent in an emergency because you've been trapped short of a hut by extreme weather. A possible third reason is that you may wish to take side trips to areas where there are no huts, and will need a tent.
There is always a chance of snow or inclement weather in February on the OLT. Of course, you could be lucky and walk the whole track in sunshine wearing shorts and shade hat.
I personally don't think I would be comfortable in the Tarp Tent Rainshadow 2 in snow or strong winds and rain, but I have no experience with the tent, so that is just an impression. You have experience with the tent so should be better placed to decide if you would like to camp in cold and damp conditions in this tent. My current 3 season tent and ground sheet weigh 3.9Kg, so I understand that when you are packing for a long journey, this is an obvious place to save some weight.
I think the best advice so far is 'somewhere in between', but if that isn't an option, you decide on the level of comfort and protection you want. Are you sure you will be fine in the Tarp Tent in snow, sleet, heavy rain or strong winds? Your call. You should always plan for the worst conditions, that way you are prepared when the worst happens. To plan for and hope for the best conditions only, is to gamble. Risky! Especially on the OLT.
