Can anyone who a Thule 991/992 give me some much needed advice please?

I’ve gone through the whole roof mounted V’s towbar mounted and now boot mounted process of bike carrying and have come to the conclusion that roof is too aero dynamically poor, the fittings leak on the VW golf and I’m a shorty… Tow bar is too expensive… so boot mounted it has to be…

I’ve got a Nukeproof Mega 275 TR and need some opinion’s about whether or not the Thule 992 will be suitable for my bike…

Any help appreciated.

Thanks.

John
