At the moment, I own a 7'6 MH moderate crucial crankbait rod, and a 7'2 MH XF worm and jig rod. I'm assuming these are less than ideal, but am I wrong in assuming that I could get away with using the crankbait rod for tossing 3/8oz cavitrons?

I'd bet you could use them on the 7'2" with a stretchy mono to make up for the XF tip.

I use some 10# Yo Zuri hybrid. That has a little stretch, and I'm pretty good at now ripping the hooks out of a fishes mouth on a hook set.

I think I would go for the moderate action, especially if braid is involved. 

The XF with a quality mono would work fine.

My buzzbait rod is a 7' mh/xf powell max and it works great. #12 yozuri and a 3/8 cavitron. Use a sweeping hook set and you should be fine.

I normally throw buzzbaits on one of two different rods. I chose between the two depending on what I'm fishing around (open water or cover)

Shimano Crucial 6'10" MH-F with 832 braid

GLoomis TWR 6'5" MH-F with 832 braid and a FC or mono leader

I throw buzzbaits like the cavitron on a MH/F with PP braid

Guess I will use the XF rod. Thanks.

I use a 5'6" pistol grip rod medium action with 1/4 oz. Lunker Lure buzz with 12 lb. test and 6:3 reel. Gets the job done...

 

Old school basser...

Honestly I think you could get away with throwing it on either rod, try it on both and see what you like better

It depends, do you have a vicious hookset? If so, do braid on the moderate. Otherwise you should probably use mono on the XF. 

 

As weird as it sounds, I use braid on a 7' M/F and I just put my tip to 11 o'clock when they strike, it tends to set the hook itself. 

It depends on how soft the moderate action is. I don't like my cranking rods for buzz baits (or spinner baits) due to the heavy hook and too soft a rod can make getting the bait up on plane harder. 

Once upon a time, I owned a graphite, medium power, medium action.  The curve was equal from the handle to the tip.  It was the type of rod articles in Bassmaster said that you should be using for throwing cranks, especially deeper diving cranks.  I had the bright idea to throw a buzz bait, reached down to grab a rod and this was the one I grabbed.  I was going to have to tie on a buzz bait no matter which rod I grabbed, so what the hell.  Long story shorter,  it cast a buzz bait great - outstanding distance, for me, with a half ounce buzz bait.  It did take a foot or so longer to get it up on plane, but that really didn't register with me.   Anyway, it was a good idea, buzz bait bite was on 7 strikes on 8 casts and I missed them all, couldn't set the hook enough.  Finally it dawned on my tiny brain what the issue was, and now I don't throw buzz baits on crank rods anymore.   I don't throw cranks on "crank bait " rods either.  I found a 7'4"  BPS extreme rod that has a lot stiffer butt section, and a less "tippy" upper section that works great for me.

 

I get the similar distances that I did with the crank rod, with much more sensitivity and distance hook setting ability.

 

That's why I don't use a crank rod to throw buzz baits.

I don't care for a cranking rod with those big hooks.  I'd use the other rod. 

I throw buzzbaits half the time in and around heavy cover, and the other half in open water. I love to use braid with my buzzbaits as it helps cast the bait further, but the catch is the lack of stretch can be an issue. Fast moving baits may cause you to rip the bait away too quickly on a strike, stretch helps the fish take the bait a bit better. Given that I use braid, I actually opt for a heavier cranking rod with a softer tip for my buzzbait needs (when using braid). If I end up using mono for some reason, I go for a faster tip medium action rod. Given your two setups, the cranking rod is fine with braid, or the jig rod can work with mono.
