The slighty lower mass of the SMW V should not matter too much. The regular DL103 runs great in a medium mass Rega RB300 as well. A lot of people in Europe love that combination. I actually have a DL103 mounted on my P3/RB300 and it works great. Can't find a better cartridge for the money (I got mine new from Phono Phono, Berlin for around $120).
Enjoy.
