1. That picture is a SP 1st stage.
2. The HP port in FSR has better routing because it is in an inclined angle pointing downward.
3. XTX-number can mean a set 1st + 2nd(one only) or just the 2nd stage. While FSR is the name for the 1st stage only. You need to confirm that from the seller.
FSR + XTX50 should be slightly cheaper. The moving part is the same between 50 and 200, the difference is minimal.
