Shiner Bock Clone need advice

The only decent looking recipe I could find for a Shiner Bock clone is as follows

5 lbs. American Pale Malt (Briess)
1.5 lbs. Munich Malt
1 lb. Flaked Maize
1/8 lb. black patent

1 oz Centenial (most likely have to use amerillo as substitute) Bittering @60min
1/2 oz Liberty Finishing @ 50min
Wyeast #2206 Bavarian Lager Yeast
1 Hour Boil
Mash @ 155 for 60min.

Does this look like it would be an accurate clone?
Would this style benifit from a decoction mash?
If so what temps should it rest at?

Thanks
