Been a while since I asked for advice... This time with keys

Good Morning!

I am debating on how to spend my keys.... I have most of the "spine" of the harmony tree done. First gem stack level, auto demon/smart demon, and auto restart are all done.

I am considering getting select mod shard type (2 more tournaments at most) but lately I have been seeing lots of people talking about bot presets being one of the best if not the best harmony tree unlock. At 4 keys a week it would take me approximately 20 weeks to get enough to get enough keys to unlock it. Is it worth grinding those keys out or should I just go for the mod shard select unlock? (obviously if I get a few decent brackets it could shorten that 20 weeks fairly substantially)

For reference my mods are:
Cannon 201/164
Armor 202/164
Gen 206/150
Core 201/164
(yes I now the distribution of levels probably isn't "optimal" right now)
I have damage, a.speed, crit, range, and DPM labs all done.
I have damage, a.speed, DM, ST, range, and ult crit masteries all done as well.

I'm working on additional CC with stones and additional echo damage with coins currently to hopefully start doing more than 1350 waves in legends to start getting back into the 9-12 slots for extra keys.

Thank you!
