Pudnucker, I was in the same position as you 7 years ago and chose the fixed wing IR first. I did my PPL(H) 2 years after that.
I think a factor of 4 is not unreasonable when you are comparing operating costs for whisk vs plank.
i:e 4 plank hours = 1 whisk hour
Insurance hurts the most but its all bloody expensive.
You will also begin to increasingly resent paying landing fees when you do have to be handled at an airport if most of your flying becomes private site to private site.
Most importantly - try to remember which one you are in at any given moment in order to avoid unnecessary bills!
