No worries mate. Sounds like you run a similar sized rig to me, I have the SbA760s and can just get two of those with my RCF 312A in for front of house, then monitors. It does for most venues, but I found I was doing a few more outdoor festivals and weekend hire for FOH was not cheap, plus collecting it etc. so took the punt on the HK as it was a really good deal. I was not disappointed.
With your X32 Compact and rack, so you run them with an Ethernet cable between so you can use the rack as a stage box?
