To re-quote my old chestnut: "Better to receive either an unnecessary warning of a dummy site/mobile zone or multiple warnings of a live site than to have no warning at all when it's needed". Load every poi file you can get your hands on if you're totally paranoid and don't mind receiving dummy and multiple warnings. In a nuvi, loading multiple *.gpi files of the same area cause no problems other than extra warnings being given. Propbably TT is the same, i dunno for sure. I know Giomen will say something like he doesn't want to pimp his nuvi up so that it lights up like a xmas tree, and he just sticks with cyclops 'coz it hasn't let him down.

Maybe if you decide to flick your TT and get a Garmin, you could load both cyclops and a reliable user-contributed database. You will get the best of both worlds and prevent some hand-wringing (both figuratively and literally). Otherwise on your TT substitute SCDB for Cyclops combined with the other.
