I'd be interested to know what you are using to be constantly full at 46 int. because for me I only manage that after whole day of foraging, then the next day I will be half empty. boar tusks or something? (I use those sometimes for reals).
Currently: Itsy Bitsy Spider, Itsy Bitsy's Web, Enthroned Toad, Uncommon Snapdragon, Wondrous Woodshaving, Thorny Thistle. That is 27k lp when they are all over. But most of the time I have Bat Wings, Uncommon Snapdragon, Seer's Bones, Mirkwood Offering, Thony Thistle, Ladybug, Dewy's Lady Mantle and Emerald Dragonfly with something heavier like Enthroned Toad.
My recommendation is to not be too picky about curios, just avoid the really bad ones: the ones that take forever, weights a lot and gives you like 2k lp cus you will probably swap it for other better curios and just lose the time. Also, even though Itsy Bitsy Spider and curios alike have low lp/hour/mw, they are worth when its quality is higher, like q15+, imo.
