spark plug heat range

I just put the champions back in... The std low-cost one l77jc4. Not looking to drop $50 on plugs.

So it's pretty unanimous that going to a hotter plug is not a good idea?

I mostly run at about 4000 rpm or more (running to the fishing grounds or pulling a tube with kids on it), but do a lot of idling through all the ICW no wake zones and other stuff... 10 minute idle just to get into the waterway.
