Comparisons between 2-fa and 2-fma

[brjohnson08]

I was wondering if anyone has had experience with both 2-fa and 2-fma. I know they are both more straight stimulants than 4-fa/4-fma but I would like some more specific information regarding the 2-fluorinated amphetamine analogs. I am particularly interested in potency and duration as well as how they compare subjectively.
Thanks
