What height stays do you have on your t2 and bikini? Take whatever they are and drop the lifter slider down to 22in and see where your at for lift.
I have a spike camp. I am only 5'7 and I get lift out of the 22in stays with reasonable loads. Its a sweet little pack, that I use for a day pack up to a weekend if the weather is nice(think summer scouting, fishing and shed hunting). The pack really sticks to your back, and almost seems like im not wearing it. Iv owned a handful of k packs and to this date the spike camp with 30lbs in it is the most comfortable to me. It hauls weight well for me up to about 50lbs (exactly where kifaru puts the comfort rating).
I would really like a late season, but I think if I was to get the late season it would end up sitting around seeing as I also own a HC4800, that or the HC would sit around. Another plus to the spike camp, is that it can be run without a waistbelt for biking or using it as a day bag. I might be wrong but with the wraptech suspension of the late season it cannot be used without a belt.
In all the spike camp filled the gap for me and gave me what I wanted. A day pack and a UL weekender pack. Something short enough to use while biking, and the ability to leave the belt at home if I don't need or want it in the way. If you cannot get lift out of the 22in stays, the late season may be a good option, although the main bag of the late season is basically the same size as your t2.
