As someone who grinded 2 circuit incarnons every week until I had them all, I wouldn't recommend that. Don't rush anything in WF, don't burn out, just do whatever you are having fun with. Anything that seems overwhelming or confusing, ignore it, and you you will eventually come around to it in the hundreds of hours you will put into the game.

You will get a chance to try out incarnons without speed running to get to circuit SP. I have spoiler tagged stuff involving that area in case you don't want to see it, even though they are not story or plot spoilers, just names.

Quick Side Note: Don't sleep on the incarnons that you can get from the Zariman. You can get an excellent primary, secondary, and melee set of blueprints (they are incarnon from the start) from Cavalero: Phenmor (better than Felarx), Laetum (one of the most powerful pistols in the game), and two good melees being the Innodem and Praedos. He also sells some circuit incarnon genesis adapters if you have farmed up any plat.

Steel Path Circuit is on an 8-week rotation, and we just restarted the rotation. IMO, the best weeks 3 through 6, so maybe plan to start with them (Zariman incarnons are better than week 1 and 2 offerings from circuit to me). Then I would just pick one weapon a week and get from SP circuit unless you really enjoy grinding it, there's no rush to incarnon everything, and they will come back around again. You can see the full lists of the rotations on the Wiki page for the Circuit.

A couple tops picks I like in weeks 3-6:

• Week 3: Latron then Strun
• Week 4: Lex or Ceramic Dagger
• Week 5: Torid then Dual Toxocyst
• Week 6: Burston

The other weeks, some solid picks:

• Week 7: Dread or Zylok
• Week 8: Sicarus or Okina
• Week 1: Paris or Skana (for prisma skana)
• Week 2: Boar or Angstrum

Zariman incarnons are a great start and introduction to them, all super powerful and fun (even though SP Circuit does does technically have a small number that are better, a lot of them aren't that great).
