G'day Alex,
I have a 6-12kg braid concept and run a 460 penn slammer loaded with 15kg braid over it - its a nice rod - typically Japanese in its action - a slow taper blank that draws power through the length of the rod, almost parabola shape in power curve puling power back through the butt - I have monstered some very nice fish on it, although it doesn't really feel like you are in control as the action is very soft, you are.
I brought the rod primarily for soft plastic jigging in up to 60 mts with up to 1 1/2 oz jig heads, it does that well - heavier jigs will challenge it as the actions is quite soft so I'm not sure if its the best rod blank for lucanus work.
My preference is for a rod with a faster taper, a little more tippy and a bit more in the second stage mid section power area - but I'm not sorry I have it.
I have an egrell s10 but I think the S10bear would be a better alternative for lucanus work although you start to step up in dollars. but when you are looking in the $300 bracket, its not a lot more to get the right outfit.
An alternatives in the same market area of $300ish, The shimano T curve is worth a look, I'm eying off a 6-8kg T curve at the moment more for SP work than lucanus - I think the action is quite suited to your purpose. and wilson live fibres have a blades and tails that is worth checking out.
I have a 8-10kg Starlo Styx squidgy snapper heavy, its is in the $100plus range but would be a worthy contender for the kind of use you are suggesting and you'd get change?
I just feel the action on the Braid Concept may not be the best for your stated application, but what suits me for feel may not suit you.
In terms of quality and build, the bindings add a bit of bling so if you like that stuff you wont be disappointed - they are a very nicely put together rod and extremely tough - like I said I have monstered some very nice snapper, amberjack and kingies on mine - the rod performed exceptionally well - surprised me actually - very forgiving.
hope this helps
cheers
Rhys
