Tree, you just missed a long week-end at Fraser Lake a couple of weeks ago! If Sparklr ever puts out the RR :Stir he may include some of the routes in that area.
Sounds as if you've explored South Side / Francois Lake / Ootsa Lake area ...I love that area - lot's of "easy" stuff (just for me). What degree of "offroad" are you looking for? We now have "Route Scouts" in Kitimat, Terrace, Hazletons, Smithers, Houston and you in Burns Lake (sounds like a floor to sleep on in each town

). One day someone will build a list of the various rides, type, difficulty etc.
As you know there are many, many FSR and trails ...just go and explore and let us know.If you haven't already, get a copy of the BC Backroad Mapbook it's a good start...certainly enough to get you lost and into embarrassing situations.
One of my favourite "loops" is Terrace-New Aiyansh-Cranberry Connector (Kitsault detour)-cross Hwy 37 - if not going the Stewart/Hyder) Mitten & Helen FSR - Kispiox - camp at Hazleton then Moricetown -Telkwa High Road - (cross Hwy 16) - Lawson FSR (?) and come out near Houston & then off somewhere south of Francois Lake - Takysie Lake ....
Sometime I want to go for a look-see up Babine Lake - Granisle to Fort Babine
Anyway...look at the map and join up the dots
