One more thing that nobody stated here , remember that F5's are not having full-state failover. From my 7 year experience I've seen situations and environments that this setup was a disaster since applications were not able to reconnect sessions after failover of F5 cluster. For me having inline is the last resort (i would run cluster in hybrid mode so we just use inline for particular vips when necassary).
Just an update to Barts' Reply above - full state failover has been supported via connection mirroring for quite a long time now - with a few limitatinos. Bart was probably referencing connection mirroring for SSL - which is indeed supported now in v12, see here:
