Canon's wireless flash protocol sucks big time.
This is the only culprit for all the difficulties you and all other Canon users are experiencing if they wish to use 2nd curtain sync over wireless. A few newer items of Third Party gear - al of them listed in this thread - do offer workarounds - but all of them are both limited in functionality and ergonomically cumbersome.
Even when they introduced their new, expensive as hell Speedlite 600EX-RT and ST-E3 trigger with radio wireless technology, Canon refused to implement an improved version of its wireless [ETTL] flash protocol, that would allow a straightforward workflow and direct control over all relevant flash parameters - including 2nd curtain sync and power zoom of flash reflector - directly on the Camera's LCD panel and flash menu.
Nikon CLS allows all of this - of course including wireless 2nd curtain sync together with iTTL - for more than 2 decades by now. It also does not stuff the totally stupid concept of "flash ratios" - "A:B" - down its users throats.
This is one of the reasons why I am refusing to invest any more money in my Canon gear. Until they got this sorted out. Or until I finally make the switch to Nikon and send Canon to hell.
