Having had two TDM900s (and a TRX850) you can see that I like Yamaha's parallel twins but when the last of the TDMs got a bit long in the tooth and needing replacement three years ago I opted for a Tracer 900 which I've been very pleased with in most respects with only the hard seat being a real issue.
Out of idle curiosity, I borrowed a Tracer 700 from Skellerns in Worcester while my own bike was enjoying its first MOT. To cut a long story short, I liked it.....A LOT! So much so that I've traded in my Tracer 900 for a new 700, it's much more reminiscent of my old TDMs (I didn't want to return the test bike to the shop after my ride out). To put icing on the cake, Yamaha are offering a free "touring pack" with the 700s purchased in April, hard paniers, tank bag, 12v socket etc.
So it's back to parallel twins again!
