Sounds like you've got that antenna pretty well dialed in. That is a lot of linear space. Reminds me of a SOTA activation I did a couple of years ago up on Mt Evans, which is naturally a busy place, trying to deploy my end-fed random wire antenna. It was really difficult. My favorite antenna for limited space deployments is of course my Alexloop, but it requires considerably more weight and backpack space. The antenna itself is pretty light--finding a decent tripod under 5 pounds and <$200 is the challenge.

I really love my off center-fed dipole, which has an incredibly tiny Balun. The long end is 44 feet and the short end is 22 feet. When I deploy it, I attach the Balun to the top of my (6 meter) push-up pole, which shortens the actual run length of the long end to about 25 feet or so, and the short end has hardly any space requirements (maybe 10 feet). With a tuner, this antenna will work 40, 30, 20, 17, 15, 12, 10 and 6 meters. Total weight for the antenna is 7 ounces. I purchased my from Tim Ortiz (N9SAB) via eBay, but they?are easy to DIY as well; lots of plans out there on the interweb. Coupled with my Carbon6 pole, total weight is just over a pound. Add another pound for my tuner and 2.2 pounds for the IC-705--still a very manageable ~5 pound kit.?

And, for ultra portable work, I also have a 20M end-fed half-wave antenna, which I have coupled with an impossibly tiny 0.3 ounce Unun kit from K6ARK ($20). That antenna probably weighs 4 ounces and coupled with the Carbon6, still well under a pound. And no tuner required.?

I think that antenna design and building is one of the most rewarding parts of our hobby. Nothing like making your own antenna and making QSOs with it!
