You've gotten some good responses already, but I'll add 2¢
Most folks (with a decent technique) gain an average of about 10 yards more casting distance per foot of rod.
Find the balance that works FOR YOU!
IMHO surf rods to target "redfish" are a different class than "pompano" rods.
And a medium heavy action (MH) rod 15-30# line is way overkill for pompano.
If you want both in one rod, try to 'step down' to a medium action (M) in the 10-20# class.
They are harder to find, but worth the effort in enjoyment.
Most folks opt for the heavier class rods because they are more available and they "might hook a bull red or black drum".
But unless you want to target those specifically (and/or sharks), you will get more use out of a 'lighter' classed rods.
I tell my clients "Would you want to catch a bass or walleye on that? Because that's the size of +95% of the saltwater fish you are likely to catch in the surfzone."
For me, pompano rods should be rated no more than 20# line, and 3 ounce lure (weight).
Rods to target redfish, etc. are anything over that. Even though the lighter tackle can manage a typical 15-25# red or drum just fine.
Hope this helps!
OBTW, if you do opt for a "Steelhead" rod for surf fishing, be sure it has the handle shown 'A' and not 'B'...
