Tonywong88, no offence, but not to many prairie folks would consider Edmonton to be the 'prairies'! I am from the Peg. It was very nice of you to offer my trying the combo though. Since you have the Kenko 1.4 and the 120-300 OS, as well as the 1.4 III and 2.0 III Canon TCs, I would be very interested on your thoughts of the IQ natively and with each of those three TCs.
Imagemaster, if I was pretty much locked in on one item and just wanted that final assurance, renting would be an option. But I really don't want to rent a Canon 300 2.8, Sigma 300 2.8, Sigma 120-300 2.8 and the Canon, Sigma and Kenko TCs! I may have to drive south of the border for a look-see.
