Recommend to use it as a Dynamic Animation Replacer (DAR) condition so that only some 2hw weapons will use this attack.
This download includes 2hw_attackpowerforward.hkx and 2hw_attackpowerforwardsprint.hkx, I recommend trying them both first to see which one you like better, remove the one that you don't really like.
