Oops... my math was a little off before.
I am working with the assumption that player's BP HR's are based upon their performances in their "home" ballpark. ARod in Yankee Stadium (BP HR 1-10) for example. But in my calculations I was using BP HR 1-20 as a base, and for ARod this should have been 1-10. So instead of losing 10-12 HR's, he actually only loses 5-6 in Petco.
Still, as a general rule however, the greater the number of BP HR's on a player's card, the greater the decrease in production in a park like Petco, and conversley, the greater the increase in production in a park like Coors.
The opposite is true for pitcher's... you can get away with pitcher's with BP HR's on their cards in Petco, as these just turn into long outs. Drese's card has higher WHIP and no BP HR's, great for hitter friendly parks, but decreasing in effeciency in Petco.
I've not used LaDuca before Bravefalcon, but have used Burke a number of times and he has always been money in the bank! IRod, Kendall, Estrada and Burke would be my 1st choices in Petco, depending on your needs and budget constraints.
