This is a subject close to my heart! I have done a bit of work on this one. Firstly most rods do not have a “jig rating”, just the normal casting rating (in many cases rating seems to be a figure plucked from thin air… But that is another subject). But some rods actually do have a jig rating.
To give you a better idea….. Take the Element Riders from Illex. If you look at the catalogue or on the rods they have a casting rating and also a jig rating. So a S210mh is rated at something like 7-35g and has a jig rating of 100g. A S210 h has a rating of 10-60 and a jig rating of 180g. In reality I find that these jig ratings are optimistic but close enough to being the real upper limit of the rod. Also adding tide to the mix adds more grams if you get my drift.
By the same token I have a P&M Kairo that I got for the exact reasons you outline. I'll have to double check the model,I think it is an S220h rated at 10-50g. It handles the heavier heads well. I'm talking either heavier heads/jigs (100-150g) or deeper water. I mention the Kairo as it is a well priced rod. I ordered it on the basis of the illex jig rating assuming it would handle up to 150g. As I say, it has worked well!
So what I would say is by using the ratings above it might help you select a “heavier” lure rod. I think that a fast action rod is best. Some of the modern lure rods have missed the need for tip action but with the ability of bending when required that comes from modern carbon fibre. What 10-40g rod did you get? By my reckoning it should handle the weight if the blank is good.
You can always have a feel off the Pezon and take it for a test drive if you wish.
