OK, if it works easily then I'm all for it! There's a legitimate comparison and contrast to consider between the Acon and Cactus P-TTL offerings though. I know you value the smaller size of the Acons Clackers, but the flip side of that are the user interface benefits that stem from the larger footprint of the V6II.
I've been testing the Cactus products just today after a new firmware update for the RF60/x flashes, and the ease of use / flexibility case for the V6II is very strong I think. The practical implementation of the different features available now under the 'X-TTL' firmware really is superb. The advantage of being able to see at all times the current active groups, their mode (TTL / M), their output setting (Compensation amount / Power level) and with a quick press in on the dial the zoom setting, cannot be overemphasised. I'm only working with a 2-flash X-TTL setup .... these advantages will increase exponentially for each additional light/s added into further 3rd and 4th groups.
The methods of selecting and switching between exposure modes, multi-group or single group adjustments, group on/off, and zoom settings is all really well designed and thought out. It really is literally 'under your fingertips' with the benefit of easily visible display information.
I do accept of course that the various issues over compatibilities with third party P-TTL flashes is a frustration, and that it has been a confusing picture for potential buyers. My own attitude to it is that the Cactus system is not so ideal for those looking to get extra mileage out of third party flashes. You might be better to keep using those for on-camera work. But if you are looking to build a new Radio P-TTL / HSS / Manual system then the V6II combined with their own RF60/x flashes is unbeatable I think.
