I saw this, pretty sure I'm going to purchase one of these but I own two frigates and thought it might make sense buying the 6.5. Haven't seen anyone talking about it though.
I have a PT Skin and Frigates. They fly very differently, the 5.4 PT Skin pulls like a truck and I at 93kg would not go bigger. Great in light air but does not handle gusts as well as a Frigate. Light fabric and tight C lines means the 777 is a joy to transition in light wind compared to a Frigate.
