Weak signal work is mostly SSB (single side band) and around the SSB calling frequency of 144.200 Mhz. Two meters can be open for SSB and other weak signal modes and signals are still not enough to break a squelch or make FM reliable.
It can be worth a try but if you want to go for distance, get a rig that works SSB-you will find a whole new world. Antennas are also usually horizontally polarized rather than the vertical for FM. The path loss trying to work horizontal with a vertical is around 25 db if I remember. Of course, polarization is less a factor once a signal 'bounces'.
