I've had pretty good luck with just the pins and sockets, and perhaps a bit of dielectric grease now and then. The nickle plating on the contacts are quite resistant to corrosion, though, even in lousy conditions such as shown below....
The DTM series is substantially smaller than the DT series, and shouldn't be too bulky on a bike.
FWIW NEVER use dielectric grease on the contacts. As it ages it create issues of its own, primarily fretting on the contacts, as well as becoming a sticky mess.
NyoGel 760G lubricates the contacts and prevents fretting. And it doesn't dry out and create a sticky mess.
