Hi.

I had a look at the information here: http://www.captainsim.com/products/b757/ and at the Online Store. From what I have read, you only need to buy the 757-200 Base Pack, which includes the FMS, Collins WXR-2100 Weather Radar and Aeronautical Data (AIRAC navigation for the FMS), the 757-300 Expansion Model and 757 Freighter Expansion Model. At €9.99 each, that's a great buy. You do not need to buy Block F. The 757 is only being sold in the Pro Line now so the Block F is there for those who bought 757 Blocks when that was how it was sold.

I only have the 757-200, 757-300 & 757-200F (Freighter) for FSX, but it looks like the same deal for FS9 as it is for FSX.

For extra help. Visit here: http://www.captainsim.com/products/product_lines.html for an explanation of Captain Sims Production Lines.

Hope this helps
