Agreed, it's almost never necessary here for me to downshift on the highway. If you do need to, I would suggest just going to 5th as it will give you all the power you want. Like carraig said, if you really want to wow someone, 4th is fun
As far as rev matching, if you don't match the revs and just drop the clutch, it will actually slow you down and give you that jerk (especially if you go down to 4th), so I would recommend always matching revs when downshifting.
