Get the bible as well. And welcome to the club. When you get the Garmin, switch from Smart recording to 1 second recording. This is very important if you get WKO+ and want to use the metrics. Smart recording or even low sample rates can really skew the Normalized Power algorithm and the 705 has tons of room to store data. BT may choke occassionally when you upload the long rides but power is more important than BT.
