Hi Ned -
I only use EF glass - so I can't speak to PL glass - My reasoning for specifying EF glass was that I think the weight variability of PL will be much greater than the variability of EF glass, which could require rebalancing vertically instead of just front/back.
Wireless FF and HD would not affect balance much with a lens change obviously.
We just got a hotlink so we will most likely be using EF motors to wirelessly FF - as it is rare we need critical FF work when on gimbal, usually I just need a preset range like "Gimme 3 feet" and then let the operator handle depth control with movement - This is obviously limiting as using the electronic lens motors on still lenses to do this can be more jittery - but again, we are rarely doing a focus pull when on gimbal, we just need a hands free way of setting the lens.
At the end of the day I prefer to keep the rig as light weight as possible, so this is another reason we go with this setup.
