I'm not familiar with this beer, so cannot comment on its clone'ness.
I was wondering about the 9.0 gal boil? Even for 90 minute boils, that seems a bit more than I would expect for a 5.5 gal in the fermenter batch. Just wondering if you have tuned your Beersmith for your own equipment (dead space & evaporation rate) or just used the defaults. Just something to check.
The grains look good to me for a Pale Ale, although I've never used the Acid Malt before. I know its used to lower mash pH when you have really alkaline water, but I have no idea if that is too much or too little, etc. I also read that it can be used to add some 'sour' character to a beer. Again, not real sure about that malt in there...
