I'd like to suggest that one very good reason for using centre-fed and external matching unit is because the harmonic pickup from nearby stations is much reduced compared to multi-band antennas. This is best implemented when the antenna is as near perfectly balanced as possible to avoid feedline pickup. A *proper* choke to cancel out-of-balance currents should be helpful in this regard.
For single station field days, I've used the Spiderbeam 807 off-centre-fed inverted V dipole on a f/g pole which is a fast way to get on air without an external matching unit to fiddle with. Common mode current is virtually zero. It's a great solution for beginners reducing the fiddle factor, ie plug and play KISS. Less to carry out into the field as well.
