Decently geared SK has 2.3k: Upgrade weapons or buy haste item?

[medievalerror]

So I recently returned to p99 after a couple-year long hiatus. I want to float back and forth between leveling my SK and bard. My bard is pretty cheaply geared (but doesn't really need anything, as my HP+ items below go back and forth between bard and SK). Right now my SK (Dark Elf, level 14) is geared as follows:

Fingers/Ears: HP+ Rings and Diamondine Earrings
1hs: Sword of Skyfire (and Crested Mistmoore Shield)
2hs: Nathsath Greatsword
Chest: Mithril BP
Face: Silvery Mask
Feet: Sebilite Scale Boots
Arms: Dusty Rusty Vambraces (mainly for +HP)
Shoulders: Drolvarg Mantle
Back: Giant Scalemail Cloak
Neck: Glowing Bone Collar
Face: Silvery Mask
Wrists: Tar Goo Strands

Empty slots: Hands, Legs, Waist (leather armor pieces)

My question: I have 2.3k to spend (keeping in mind that I want to be able to solo when needed), should I: 1) Upgrade weapon/s (perhaps to a wurmy?) or 2) Buy a haste item (SCHW or the cheaper and lower haste Swiftclaw Sash), or 3) Some other option I don't know of (such as filling in other armor pieces)?

I also have the option to hold off on haste item and do the quest for the Swiftclaw Sash when I get to 25-30. Has anyone done this quest? Any suggestions? Thanks for feedback!
