anyone here done the transition from a helo, to fixed wing with a ‘control column’ (not yoke)? Easy/hard?
Not sure if you are concerned about flying FW with a stick vs yoke, or the transition from RW to FW. The former will be easy. (In fact, stick vs yoke, left hand vs right hand all easy and quick to adapt to.) The latter, given that the PC-6 is a large tail dragger will potentially be hard if you have little/no prior FW experience, and medium if you have significant FW experience but no tail dragger experience. Have never flown a PC-6, but other tail draggers from Pitts to DC-3 and they can bite faster than you can say "ground loop." 
This is not something you are going to get genuinely good at (able to tackle challenging wx with confidence and skill) in a few days or weeks - more like months or even years depending on how much you are flying. Mastering a tail dragger was far more challenging than anything I have done in a helicopter (so far). If you were transitioning to a PC-12 your life would be much easier!
While all tail draggers have considerable potential to destroy a pilot's ego, some are a bit less demanding than others. As others have suggested, you may want to do some early training on something a bit less expensive to fix than a PC-6. Of the taildraggers I have flown, the Citabria/Decathlon series was the most manageable. (And perhaps surprisingly, the DC-3.) The other end of the spectrum: Pitts S2A, Cessna 305F/L19 Bird Dog. However, these aircraft are intended to be flown by humans, and it can be done with diligence, patience, and expert instruction.
