Cumara 6/8" MH vs Magnesium 6'10" MH.  

There's a difference of 2" but which of these 2 have you tried?  Does one have better sensitivity & is one more of an all around rod?  Are the guides similar or different?

Which of the 2 do you prefer?

Try comparing to Kistler Helium LTA rather than Magnesium.

Cumara/Magnesium, take the Cumara.  Cumara/LTA, I would lean towards the LTA.

I have the same model Cumare and a Magnesium in 6'6 MH. Not the exact match you were looking for but close.  In my opinion they are very similar. They are both outstanding rods, but if I had to choose I would go with the Cumara.
