Hana SL or ML?

I am currently running a Hana EL cartridge with an Acoustic Solid turntable and Jelco tonearm. Phono stage is Sim Audio. I am wondering whether to go to SL from EL or go up to ML directly. 

Anyone had experience running both SL and ML carts here? Going to ML, is that significantly better than the SL?

Thanks in advance!
