Take anything you like from my code. I'm probably not going to enhance it any more so you can even take the structure if you want.
Travel starts at 5 energy per step and that decreases based on agi and end down to 1 per step. I had also considered changing that, perhaps starting at 4 per step and dropping down to 2 per step. One possible variant of the guidance spell could change change this cost.
I seem to remember a bug report where the hunter bonus was inflated due to miscalculation. That might be worth checking out. If you really want to balance out Strive though I'd say the mage bonuses are the last thing to tweak after everything else is sorted.
