Book of Blades - rough notes
I really wish I had paid more attention to weapon combos before i hit 80. But here are good weapons (some from a non-clan store!) that kick butt once you hit the 70-80 up range. Skipped the Aardweapon till level 120 intentionally, really want to get a good feel of mudload weapons as any decent ranger should.

70 Erato's Awakener of Desire from Bard Clan shop
flaming whip (wreaks havok on Anthrox trolls and vamps)

81 Terpsichore's Whirling Lyre (Bard)
cleave and vorpal

85 Sunblade (Dark Light, Orionis Weapon shop)

slash with flaming flag, ave 117 dmg!

With the SunBlade as your primary, you can wield Erato or the Lyre in your off hand which is damn effective.

The level 90 Trusty Sword from the Regular Patron at Jenny's Tavern is useful in getting more hits on elusive targets - +10 HR and adds +3 to 3rd/4th/5th attack as well.

Backtracking to StoneKeep for the level 80 rusty broadsword for it's nodisarm, 100+ dmg and bash damage.
