OP here. Thanks for all of the generally positive comments. To the snarky among you, thanks for the entertainment and waste of bandwidth.
I have had a few more chances to play these strings live. My goodness! I DO NOT mean to be a fan boy, I take those kind of comments with a grain of salt, but the statements that these get better with age are really true - if thye are what you like. I am about three weeks in or so and it truly is an experience that ages well.
Let me reiterate what I use and am going for stylistically: solely finger style, main bass is a 2015 Am. Std. Precision (strung thru body as Jason said they would), GK MB200 amp (hi and lo mid eq points are 1K and 250hz and both are boosted 3-4db, treble and bass in true "flat" positions or slightly less), 2 home brew cabs with 3015 Kappa's (non-LF) - no tweets or mid driver. Add in the TI strings, and for what I like to hear (fat but articulate bass that is mid-forward and not scooped), all of these things work together well - after playing bass for 21 years and spending thousands playing with my eyes and struggling to figure out how things are intended to work and how they work together in the absence of awesome internet guidance in the early years like this place, I feel like I have amassed enough knowledge to put things together to serve my purposes well as opposed to working against the way things are designed to be that I was ignorant of and wondering why I was frustrated.
Again, TI's may not be for you in the least if your goals are different than mine. Reading the list above, it is easy to think that I am a vintage tone freak - maybe I am, but to my ears, from country (all forms), classic rock, modern rock, hymns, contemporary Christian music, blues, jazz, R&B, whatever, I think the strings and rig covers it all well. Jaco/Claypool/Geddy/Clark/slap/fusion/distortion/detuned I ain't, but otherwise, this set up feels like the right tool(s) for the job I enjoy doing. Maybe I am doing it wrong, and to some of you, undoubtedly, I am, but hey, I am happy and the room is shaking with glorious articulation and warmth. Bring on even better tonal days ahead!
