I do not have as many as you. I peaked at 52 before our crappy August arrived.
I sympathise with you. The last couple of years have been harsh.
However, also being a newbie, I am still learning fast and believe once you have a number of hives, Rape seems more trouble than it is worth.
Constant monitoring, swarm overdrive, honey setting hard in frames, honey that (IMHO) is not really that great, just does not make it worth it. (small doses are ok)
I am still expanding, but my apiary's are surrounded by ancient hedgerows, a very large nature reserve and overgrown streams. when (if!) we have the weather, clover comes in fast. I choose to avoid the rape whenever I can.
I will never get as much as the hives that sit on rape, but there is less management allowing to keep more hives of (again, in my opinion!) good honey... swings and roundabouts. My best hive this year = 145lb (no rape!)
Although the honey is a nice side line, I can't imagine it as a full time wage.
Try a few static apiary's away from the rape and see what difference it makes.
