Netgear GS724TS Questions

Hello:

I am looking for some information from real-world experiences with the GS724TS switches.

1) How well does the HDMI "stacking" work on these? Any tips/experiences with this?
2) With HDMI stacking, and 2 switches, would I only use one HDMI cable to connect one set of the up/down ports or would I use 2 cables and go up-down and down-up?
3) With the GS724TS in a stacked configuration are you able to do cross-switch LACP groups? I.e. Switch 1 Port 1 and Switch 2 Port 1 are in the same LAG/LACP trunk?

Any input on this would be greatly appreciated, looking to do some low-level testing and these switches seem to be in the sweet spot for affordability while offering a pro-sumer level of features.

Thanks!
