Just my experience over last three days,
have a 2.4m Prime solid dish ( Portuguese), and originally set up on Invacom twin c120, However changed on Fri for an Invacom quad, C120, had great difficulty in getting the balance on skew for CH4 and Eurosport, could only get one or other, also found Sky movies became unstable, Lost BBC2 and didnt see again until about 8 PM.spent all day adjusting and really couldnt improve, so on Sun changed for another Quad, and still no real improvement, put the Twin Back ontoday, and now have all back, although BBC 2 since hour change does not now come in till about early to mid afternoon, then stays in all day with a little drift at about 5.30 ish local time,
So my conclusion is that for my current setup the Twin is the better performer,
As to the sharp, have tried the single and found it to be good when adapted with a C120 feedhorn, however working on adapting a twin, as I have had very positive reports from Digital satellite in Benidorm who say that it outperforms the INVACOM TWIN,, will advise when I have finished.
