Instead SQL Server 2008 Integration Services Problem - Design - Solution teaches you how to use the tool. It's not a book for beginners it's a book for intermediate and advanced users.
You may have built countless packages during your career and think you're pretty good. That may be the case but the authors too have many years of experience across multiple projects and they've learned what works best.
Even advanced SSIS developers can learn from this text. It might be the case that it validates your approach. if so then great. If not keep reading.
Each chapter covers a different problem. I particularly liked Chapter 2 - SSIS Management Framework Design from which I've used copied the audit schema and framework to use throughout my SSIS development. Chapter 6 - Data Cleansing Design is also good and we're building a generic ETL cleanser based on advice in this chapter for a single customer view implementation. Chapter 9 - SSAS Processing Architecture describes an excellent method processing OLAP cubes using XMLA. I'm really keen to get this implemented but time constraints on my project mean we're still in a drop and rebuild model.
In my opinion this is the best SSIS book on the market.
But it. Read it. Use it.
