I have a
Golden Mean Earthshaker and its good for cheap seats.
If you want something more pimp, then how about the expensive big brother over @ Evergreen? Their
PHPJ410 is only rated to PE3, but people fish the PSP410 to 80lb, despite it being a PE4 rod, so surely you can squeeze an extra few pounds out the OH model?
Another option might be the
Synits, they look really nice and I'm thinking of getting a heavier one for sambo season myself.
Its going to be really tough getting those big jig ratings on a PE4 rod, the earthshaker done up to about 300g, its not happy with them, but as long as they're reasonably point, it can take it.
Edit: ahh I see that smith you're considering is PE3-5, fair enough.
