I took my new antenna up to a summit on Skyline Drive yesterday and worked for about 45mins, making 17 contacts on 40m, 20m, 17m, 15m, and 12m. I made DX contacts on 20, 17, and 15. All SSB at 10w. I think the antenna works.
Today I went to HRO and picked up 30' of LMR-200 and some BNC connectors to make a new low-loss coax for field use. I've been doing my testing with an RG-8x cable, but it's just too bulky for long hikes. The LMR-200 is the same diameter as RG58, but has less loss than RG-8x. The only downside is the solid center connector, but as long as I don't try to wind it up too tight, that'll be fine.
I also ordered a 0.5"x12" aluminum rod from Amazon to make a lighter ground spike. The current one made with .65" steel is over a pound. Aluminum won't be as durable, but it should be good enough.
This new antenna kicks ass. If I can get the weight and bulk down, it may become my default antenna rather than one for specific circumstances. It goes up quickly and really gets out there.
