Chavez,
You bring up some great points. The main one reminded me I'm already jonesing to get back out there and I just got back! LOL
Oh and BTW, forgot to mention the Helium I select for top-water will be a dedicated rod (not dual use). Which is replacing a short handled 6'6" MH loomis. Guess you could call Top-Water my confidence bait. I keep one tied on always, because I'm an opportunist. When I hear a fish crashing bait, I'll almost always grab that rod and send a bait sailing just passed the zone. It just works for me, can't find a more exciting way of catching fish than to literally see and hear them crush a big top water plug.
Did that down in the glades and had something that commanded my attention charge it, but missed. Normally when that happens I'll twitch it once n' pause waiting for a second strike, then continue this pattern or a slight variation of it. Which gives those big reds time to roll over and strike more accurately. I did exactly that on this trip, but much to my surprise I saw a sharks nose come up out of the hole. Mouth wide open as she swung 'er head sideways to inhale my bait! First time a shark has ever done that to me n' judging from the head, I'd say a four footer. I nearly freaked! LOL I tightened down on her and tried to cross 'er eyes. Instantly line was peeling off the reel, heatin' up my thumb. My bro-in-law (aka SuperSpook) is over there doin his best Capt. Blair impersonation, "Music baby, Music....we got Da Mogan" Which you really gotta see and hear to fully appreciate LOL Then my favorite part, "this ain't no bass fishin' show, it's a saltwater fishin' show.... bruthaaaa"

Finally he fired up the motor to help me recover some line. Not having on a steel leader, didn't wanna put to much pressure on the fish. Fought it for ten minutes before it roughed up my flouro leader. Then poof, it swam off with a brand new lure. Crazy how all the excitement can make you shake! We all were lookin' at each other laughin', just a hoot we thought. We weren't even shark fishing, but they were thick this year. I have pictures of a 7' lemon shark we caught near the mouth of lost man's river, and pretty bizarre story to go along with it (Scanning soon).
Anyway, A few things I've noticed about top water rods.
*Handles
Using a long handle on a topwater plug while walkin' the dog. Feels clumsy, fatiguing, and irritating when it keeps bumping your side while standing on the front deck, rod tip down. So I agree completely, a short handle is a must!
*Rod Length
Throw a 5/8 Oz spook (or dog) as hard as you can with a 6'6" rod then a 7' rod and invariably you will find little to no difference in distance. Both will send it a mile. The distance on these particularly heavy plugs seems to be more effected by aerodynamics, wind and spool resistance, rather than rod length. Because, the initial resistance (moment of inertia) is broken easily by heavy weight lures.
*Rod Stiffness
You covered that perfectly, and I totally agree. Trout often snack on these plugs also and they definitely require a medium to light action.
Almost convinced me on the He70MC. What's the handle length? Would be nice when you click a rod on the product pages if it mentioned handle length on each and every rod. Another general rating that's missing is recommended line weight, and lure weight.
