talk to me about the russian 91% (or others) vs 3.1es -- airflow

[esoxhntr]

I have a KFL+ v2 from ehpro and a fasttech kayfun 3.1es

I much prefer the 3.1es due to the better airflow. I'm a lung hitter.

Where does the russian 91% fit in terms of flow? Are there other 'free-flowing' tanks that you would suggest?

I do drip (have a magma and a plume veil) just looking for another tank for on the go.

hmm talking to myself here. seems the lemo is popular due to the airflow.

no opinions on the russian 91%?
