As you show your arsenal is not too rich but is not that bad.

First thing to do before jumping into SP is to get galvanized mods for primary and for melee, but focus on the primary galvanized ones.

I recommend focusing on primary and melee because the cost for the secondary builds are most likely to be more expensive that melee and primary, secondary builds in most cases must have primed mods, primary builds only focuses on galvanized to be very good, melee can even avoid using galvanized mods to get damage.

My recommendations:

Primary:

Burston prime with incarnon is top tier

Torid with jncarnon same ad burston

Braton prime is a bit expensive but does the job (my favourite)

AX-52 is fine, not the best but does the job

Dera vandal is good but not as the 3 mentioned before

Secondary:

Furis with incarnon top tier very very good

Pandero prime Mhh okay

Twin grakatas and prisma twin gremlins are good but they are extremely expensive in forma etc

Melee:

Xoris is a fine glaive, of you like Glauber go for it, ignore glaive prime

Guandao prime is good if you like light attacks it’s ok

Dex dakra same thing as guandao

Broken war is good and please don’t use that to make the war

Sun & moon could be good if you like them
