Having used naked "mostly" for years now, I would second your use of a naked "in black coffee, you can taste everything". I also find it affects lattes noticeably if there is anything left in a spout (i.e. one non-rinsed previous shot).
Some general personal observations for you (& CS'rs) "home use playing" (YMMV):
Nakeds have a lot less effect on darkish roasts & blends. The lighter the roast or the closer to single origin, the bigger the difference. All the below really only apply to light / medium roasts, as I only do dark roasts rarely these days.
The fresher the roast, the bigger the difference.
Going VST and grinding finer multiplies the difference a naked makes (for the better). The combination is really easy to measure with a refractometer. For a normale: Standard aftermarket baskets in a spout: circa 15% or often less, naked: up to 17%. VST spouted: from circa 16% to 18%. VST naked: 20% to 23% extraction ratios.
Progressive tamping also widens the difference, as well as the obvious preventing channeling / spraying.
Sometimes I wonder if using a spout allows you to be careless and at least some of the difference is due to unknown channeling.
Just a few thoughts for experimentation / comment.
