I've used the OFM maps for TABR and TCR and most other stuff. I think they're pretty good but the "pink line's" contrast on the 1030 when night modes kicks in is maybe a bit worse than the Garmin maps. Does depend what you're surrounded by, ie. town or fields.
Thanks guys, got open maps up and running on my Edge 1000, despite the garmin update taking like 21hrs to complete first.
I went for the bicycle routable one, not sure if that's good or bad yet. Seems to be a bit easier to read than the others i had.
