I will be going in as a contestant on this one, as this is one of my favorite classes.

Before I do, I request some rules clarifications on this:
The lash deals 1d8 points of fire damage to a target within 15 feet on a successful ranged touch attack
1) It specifies that the Flame Lash is a Ranged Touch Attack. Does this mean it is inelegable for the following: Power Attack, STR to Damage, ability to wield it in two-hands, or does it operate as a Weapon-Like Spell (or in this case, Psi)-Like Ability in all regards?

2) The entry for Flame Lash states that it may do damage to a target within 15'. Does this mean it can strike at 5' and 10' without penalty as well?

3) How would a size increase of the wielder affect the size, reach, and damage of the Flame Lash?

I've already got my build set up, should be fairly unique. I may take a hit on the Power category, but I should make it up in Originality and Elegance.
