The fitter recommended using a left+right power meter to get some ongoing feedback about progress with improving the balance in power output. I'm thinking of using the new Vector 3, but not too enthused about switching from my Speedplay pedals. But, I see this as a worthwhile investment?
First, have you asked your fitter (or maybe PT) about whether you have any reason not to switch?
I wasn't thrilled about switching from SPD to Keo cleats to use Vectors, but I did. (I have V2.) I even had to buy new shoes.
Overall it was a very worthwhile move. I like my wheels including hubs, and my crankset, and I want 100 % coverage, so that leaves pedals for me. Having power data was worth the switch for me.
You asked about an investment; sometimes it's nice to look at the icing on the cake. You also get a fantastic training tool, probably the best pacing tool available, and knowledge of how many calories you're burning.
