My weapons can't go any higher without hitting the G1 quests, unless you mean what kind of weapon I use: that's switch-axe. I'm thinking the EX Los armor or Akantor armor. Leaning towards the latter honestly because of sharpness +1 and I don't loose my earplugs. I would go down to only normal ear plugs though.
Yeah, I just meant what type.
I was a bow main up through the end of high rank but then I migrated over to Switch Axe. I picked up the weapon (and thus crafted equipment) as I straddled HR7/G1, so I was in your exact position.
As you probably know, defense is tiered to Low-rank, High-rank, and then G-rank. So, while you might see some nice skills with HR7/Rarity-7 equipment, you are almost certainly better off waiting a slight bit and crafting a G-rank set.
To answer your question more directly, I personally went straight from High-rank Tetsucabra (the mule I learned the weapon on) to Regios X to Nargacuga X. Seregios is the G1→G2 Urgent, so you will fight him a million times if you're playing online with randoms in G1 rooms, which makes it super easy to craft. It is a great utility set, especially when paired with the Seregios SA. The specific downside to it is that
everyone uses it at that point in the game.

IMO the best skills for Switch Axe are Evade Dist, Evasion +, and Handicraft (as will all Blademaster weapons), making the Nargacuga X set virtually ideal.

And from there you can mix in Kushala parts and get a bit more gem freedom.
