Did we meet on trail, mine being the big group with the Scouts out front and the old fella with the big pack walking sweep? Whenever folks are willing to chat, I always try to engage hikers with the boys, particularly where you can underscore or beat my exhortations for light and limited gear!
Since you had fishing gear, I think we missed you. Believe me, we had fellas that would have grilled you on your baits and technique: we call this trek "The High Sierra Fishing Expedition".
By the way, I'd EXPECT you to be warm and dry with your teeny little Kleenex tarp and dental floss guy lines, because you're into it. However, it didn't go without notice that two of the groups we had fun chatting with proffered that they'd been wet and cold using that gear. Similarly, one of our tent crews was sloppy with their (freestanding) tent and had plenty of wet gear the morning after those rains on the 17th. I think it would have been fair to presume they'd have been dry, too, certainly if based on the square footage of vestibule space they had!
Mono County SAR bedded down in the trees near us, on the north shore of Garnet, for that storm on the 17th and used a guyed, flat tarp with one in a bivy/bag and the other just in his clothes. The dude without bivy was soaked by that windy rain, but a sunbathe in the morning boosted him right up. The pair punched over the westerly, XC pass to TI and then up to North Pass, looking for a pair of hikers reported in distress (not found).
To me, it's all about the gear that I can make work, and reliably so. When the wind's blowing rain sideways and I am dry and situated inside my Copper Spur, or when I'm comfy sleeping on rough ground because my big cush inflatable pad is awesome, or enjoy a sunrise fishing with a cup of coffee while sitting on a stool rather than a wet rock, these things justify themselves just as much as my more traditionally-recognized "UL" margarine-container mess kit, 22g knife, ti stove and zip-lock tackle bag do.
Either way, despite our full-size internal- and external-framed packs, we only saw three groups out there on the limited portion of the JMT we traveled that appeared to be packing lighter than we were. One little Japanese lady with a face covered in white zinc had a pack that was about 2/3 her own height (and she jammed) and we passed 4 dudes with giant Gregory packs loaded with a 5-person inflatable raft, oars and a bellows pump. Those energetic fellas were going to fish the deeps in Garnet and TI. Each of the three "UL Crews" we encountered looked happy and fast, notwithstanding the shortcomings of their Kleenex tarp and "cheatin'" on canister weight.
(I slipped rocks in their packs when possible.)
