@Smyles do what you feel doing best with your watch choice. That’s a separate thing.
I’ve already explained why you’d end up with two workouts in stryd, and you’re right, completed workouts will be duplicated after doing Stryd offline drying sync, however new ones won’t.
My setup is:
Stryd account connected to Suunto account.
Suunto connected to TrainingPeaks.
Stryd pod used as a Powermeter on my watch, but NOT through S+app.
do your power-based Trainingpeaks guide on your Suunto, once finished, workout will be in Suunto (no stryd metrics) and in Stryd power center (no stryd metrics yet either).
Next do offline Stryd sync, a second workout will be there temporally in Stryd power center, after a few seconds, this two will get merged by Stryd and only have will remain that has all full metrics.
Stryd air power is nice, but not sure how it helps executing a workout by monitoring it live, Stryd real time power already accounts Stryd air power though, however, if this is a deal breaker like it seems to seem to you, go ahead and do what feels appropriate.
I completely understand this, I’d be returning a Pace Pro 3 if I’m used to Suunto ZoneSense feature for example and it wouldn’t be there in Coros 🙂
