Most of the rods mentioned above are WAY overgunned for clean to cleanish ground work. Personally I use my Primo Synchro or my TTLD for almost all my clean to mixed ground fishing (or the two together if fishing two rods) though I have to say since I picked up a GT tip to go with my M4 Evo butt I've been using that one quite a lot as well (as one of my old politics lecturers used to say: "choice leads only to confusion")
I don’t know the proper reason the LD rods came about and always assumed they were designed for “little” people/those with small hands. I’m an average built lad at just under 6ft tall, 13stone, normal hands so did not think they were for me but after having a go of one it was brill.
A lot of lads make fishing hard work in my opinion and I’m all about making the experience better. I use as light gear as possible, full FS convert now as well and as long as you’re not a super serious caster – why not go for LD, its so light and easy to use. I’m not a fantastic chucker, but using my TTLDSM and a FS reel which I am still getting the hang of when it comes to a power cast, I am at 125 yards on most casts with a 5oz. With an E1000, 6-7oz and a multi I am over 150 yards – but that takes a lot more effort!
TT LDs are hard to get a hold of mind and rarely come up but what a rod. It can be used for clean – mixed ground no bother, I even use it for a bit of extreme lure fishing, with a 3oz weight it just flicks leads hilarious distances with no effort.
I’d encourage anyone to give an LD rod a try – especially if you’re an office worker with delicate hands

The TTLD was the brainchild of Keith White, he of X-Cast and Jersey Casting Club fame. Here's the story in his own words, nicked from the myfishcasting website...
"well, now we can talk about properties often lost in modern fishing
rods.
When I went upto Century to discuss this rod we had an in depth chat
about not producing something that would suck the life out of the feel
of fighting a fish.
I can tell you, this rod bends but....
it's far beyond being a gutless wonder.
Its like a fine combination of fine soft bait rod, usable in light mixed/ clean
ground, surf, match, estuary etc whilst being able to hold onto a wired
150g sinker in fast tides.
This is where the rod is different.
It has what i would like to describe as a long tip.
In little tide, the tip just sits over, but, add tide or tension and the tip
stays long and takes a fair amount of rod with it. This means that in swell
the rod sits stable as there is more rod doing the absorbtion of any
interaction against the line.
I spoke to Dave about smoothounds often changing direction right under
the rod top and we discussed building the gearbox to suit such direction
changes without either the fish having it's head or the angler loosing
control. It achieves that.
Now, for smaller fish like red mullet, this rod will work, but if you are like
me, you'll prefer something altogether lighter for those.
Bream however....
I haven't had a bream over 2lbs this season yet, but I tend to use 3 or
4 oz sinkers sometimes at 2 rod lengths, sometimes at 100 yards plus.
Bites are very, very easily seen on the rod whatever the range and for
shore bream i use circle hooks now. they just pull the rod over mate.
It's not too long before the Triggers will show either and I'll be using this
rod for those too.
It is, in essence, the ideal rod for channel island fishing bar the very small
and the larger species like conger.
Rays go well on the rod but.....
If you are high above the water, you wouldn't want to be trying to lift
anything BIG.
In fact, and I shouldn't really discuss this but, hey, what the hell...
I have done multiple tests lifting doggies, sometimes in double shots
up rocks and faces upto maybe 8 to 10 feet high.
The rod curves right over into its gearbox and .....
I think, this is a safer prospect than say lifting a doggie on a stiffer butted
rod where the rod flex's so far then halts putting stress all in one zone.
I'm not advocating people lifting fish in this fashion but, in the real world
it WILL happen so I tested for it.
It is a REAL fishing rod. It puts the fun back into sea fishing.
Come on, we fish at range, sure.. but we don't need 20lb line and
200g sinkers to catch pouting do we. I've fished for huge fish in the USA
on 10lb test and never snapped out unless something else went wrong.
Ever tried breaking 10lb line tied to a post and pulled gently back with a rod?
I have and it is EXREMELLY difficult.
This rod is slim, agile, sensitive and fun.
Fishing rod first but....
more than capable of applying big grins to anyone prepared to take the
time learning to achieve a smooth casting technique.
for those who haven't yet hit 250 yards, this should be on your list of
rods if you have any aspiration toward improving.
Its not a magic bullet but its close."
