~10 watts into a dipole is plenty for both CW and modern data modes. SSB is harder but still doable. ARRL is right it probably limits its use for emergency interop, and I do support their proposal to keep the 100w limit. However, if the FCC goes with its original proposal I won't lose any sleep. Perhaps it can be a haven for QRP operations. The propagation on 60m is quite good day and night.
