Just to add another data point, I have the Tassels Color 8 V-Tips on Truflare. I tried them on in store and based on my fit it was recommended I go TTS (9D). I'm an 8.5D Barrie, measuring 9E on Brannock. I probably could have gone 8.5D on Truflare but I find that TTS is very comfortable without being too big. Give the guys at Tassels a call or send an email. They're really easy to communicate with.
