Dont own the Superfly BigT but have flown one on several occasions. One of our flying group, a member on here, got one and was disappointed with it and he has several years of trick kiting under his belt. Tried everything until eventually he replaced the bridal with a reverse turbo bridal which did improve the kite. Also the SF doesn't have roll bars which are a great advantage on any kite particularly for a beginner. The web is full of various flight reports, not all good, about the SF so with that in mind I think its best for a first kite to stick with the DS which appears to have everyone's endorsement. I think the SF now comes with the Reverse Turbo fitted as standard.
That said we all know what the SF can do in the right hands, its a very capable kite, its just were not all as good as Chris Goff when it comes to flying one
