Fire Strike first or Curtain first? x.x

I did some calculations on the damage I would be doing if I went Fire Strike first. This is lukless with an Ele Wand 2.

70 (Pillar): 3416-4655 to Fire-weak, 2278-3103 to neutral (MP3)
75 (Strike): 4375-6886 to Fire-weak (Blue Kents) -13% level penalty
80 (Strike): 6735-9079 to Fire-weak (Blue Kents) -8% level penalty
87 (Strike): 9473-12682 to Fire-weak (Blue Kents) -1% level penalty

So I'd be 5hkoing Kents at level 80 or so and consistently 4hkoing in mid-8x. I'd also pretty much be stuck at Kents until mid-9x. With some improvement of gear I may be able to 3hko pretty often in the last few levels there. Does that seem better than Curtain? It would definitely be faster for the first 10 levels but I dunno about later on. What about Strike for a strong mob skill early -> Curtain so you're set up for late 8x? With the extra INT Blaze Wizards have they may be able to mist higher level monsters earlier.

My equips are pretty low-end since I don't play a mage, but I don't think gear should make too big of a difference. It may take an Ele Wand 1 to make this build work.
