Does anyone know what kind of warranty these come with? 

 

And would you suggest the 6'9 MHF 1/4-1 or the 7'1 HF 3/8-1.5 for 3/8oz jigs, mostly in open water around rip-rap and fishing laydowns. Maybe some heavier fishing (1/2 T-rigs) around coontail. 

My guess is a 5 year limited warranty.

I got one in H, the frog rod. I feel Daiwa rods are a tad stiffer than Shimano's for the same ratings.  If your main lure is 3/8 oz, and if they are trully 3/8oz, that's more like 1/2 oz with trailer and everthing. Probably ok with either one, buy maybe MH is safer bet? When I add a rod, I usually think about what I already have and go from there.
