Ricoh Richo GR and Nikon Flash / Wireless flash capabilities

[uptime4downtime]

Can any Nikonite, or strobist type photographer tell me how they work with the GR? I've got SB800's etc, and a bunch of triggers (TTL and non-ttl such as skysports) - be interested to hear from anyone using GR with flash on a regular basis (off-camera or on camera considered!). Thanks in advance. Rick
