Not to sound repetitive...
But you are far more like the people here than you think. When I joined last year (also after lurking for a bit) I had been poo-pooing the UL idea for several years, thinking it involved sleeping under a rotting log and eating cold dry grains and powerbars. Then I actually ran into a couple of ultralighters (or shall I say they kept passing me on our 5-day hike...) who had these teeny packs and gym shoes and I thought: how in the world can they camp with such tiny packs? And then I saw their camp: they had a stove for good hot food, they had utensils and mugs of hot cocoa, they had a tent, sleeping bags, pads, they were even eating s'mores around the fire.
When I got home from that trip I started to research...and found BPL. Then I started to realize that being UL had nothing to do with sacrifice and being cold, but rather just thinking about what I needed, buying way too much really, really cool gear and taking it on long hikes where I can experiment with what makes me happy.
I too sleep on a full length blow up mattress, I frequently take a camp chair, I take a huge camera, I take zero days and read BOOKS! I am not cold, I eat good hot meals and have a hot coffee in the morning and sometimes even a shot of something special in my tea at night.
It took about 4 complete re-dos of my gear over the past few years, but I did make the move to a cuben tarp and a quilt...but do you know what? I did it not because they were lighter...but because they work better for me.
So MY advice would be to stop paying attention to the gram weenies, but do make sure you keep an open mind about the new gear you buy. I like the quilt because I hate hate hate being constricted in a mummy bag...and that is the only reason I tried one. Granted, it is lighter and that's great, but I have really just been trying to find better gear that works for me. I resisted a frameless pack, but guess what? It is SO much more comfortable for my bad back and pointy collarbones that I am a bit disappointed in myself for resisting it so much and carrying those framed ones for so long and hurting myself.
But again, that's just MY story...and we are all here to just learn about gear you may never have heard of, to ask questions from people who may have made some good mistakes before you, to learn about food and hiking styles and ways to make stuff and cool new places to go hiking.
Congrats on getting this far, and welcome to BPL
