Dig into those FoxPro Podcasts RSG... Especially the ones with Torry Cook where he and Jon Collins do the breakdowns for each season. Right now would be the Breeding season breakdowns and I think they have done 3 of them. They also always mention the actual sound files and the sequences they use them. The latest is a breeding season podcast with Big Al Morris. Big Al has my respect for his accomplishments, and he's got a big personality, but you'll get more useful information from the Torry Cook episodes. Just my opinion anyway.
Stick with it buddy. You already know the hardest parts of the game from your previous years of calling. Adding vocals correctly into your sequences at the right time should only add to your success. You'll be stacking them soon!
