3/6NL - what do u prefer ?

[VitoT]

played with villian more then 300 hands, i have him on 26/16, he is very loose with his calling range, but shutting down if you play back on him, and i think he is a solid player, i won most of the hands we played each other and i think he is a little bit fraustrated with me.
