Start with TT sword, when you can max the falcata buy a couple of those, they don't last long, but they are stupid cheap and a decent UL weapon. Any point you could get a melee trauma 1 (UL), that will fit both. This sort of weapon will fit small daikibas nicely. Once you get to lvl 15 I recommend taking on the armatrix melee range, you can buy them between 105%-110% quite often on auction and you get the benefit of using ammo. LBs might be a little overkill for these mobs but the sb blades will do alright if you get some carry over skills to use them.
Just avoid buying non ammo burning L weapons at any real markup, it will kill ya. If you loot any Isis LLB/LSB within your lvl dont TT them, cycle them out.
