Turbo Trainer Advice

Remind me again who owns the ANT+ protocol?

Ah yes good point. Well, I did start by saying I knew nothing about it! It's hardly the only part of the internet suggesting that though, including Wahoo reviews (despite the acceptance that BT is better technically, as you said). I will have to try it again myself (I don't think it was even a valid option when I first attempted it)..
