What exactly are you looking for in the build:
Survivability? Damage output? Aggro Control? PvP team/solo play? PvE team/solo play?
I'm guessing you're mainly built for PvE teams due to taunt slotting and the lack of Focussed Accuracy. If that's the case, then you'll get far better surviability from Tough and Weave than Resist Elements/Energies. Taunt would normally serve a tank better with recharges rather than durations, since the duration on a taunt is very long already (>30 secs) and you just KNOW that your suicidal blaster teammate is going to wait until you've just used taunt to pull aggro from another mob... 
I'd also try and get an endred into Temp Invun and Unyielding, and possibly swap out a taunt duration for an endred in Invincibility. None of your toggles currently have end reduction in them, so combined with hasten you will likely find yourself running low on endurance before conserve power.
Overall I'm not too sure what your're building towards. It's not particularly survivable in terms of being able to take a pounding, though it's very mobile. You have PvP attack accuracy slotting, but you've skipped Focussed Accuracy and have only PvE slotting in Taunt... is there a character concept involved?
I've got a level 50 INV/SS built for PvE that I'm extremely happy with in terms of damage output, aggro control and survability. I'm not particularly familiar with the stone melee set but I'm sure could help out with the INV bits... only problem would be that I'm really not sure what you're looking for in your tanker!

'Fraid not MaX, I've tried Aid self and I get far better return from Tough and Weave in PvE.
Tough + Resist Physical + Temp Invul comes to 90.5% S/L resist. That's the resistance cap.
Weave + Tough Hide + Combat Jumping comes to about 19% defence before you factor in Invincibility.
Now Unyielding will offset that number slightly, but herding any normal mob with invincibility will make your survivability literally skyrocket. The slight defence against Psi from CJ and Weave (11% ish) also helps when fighting Carnies and Psi Clockwork, especially when you can get a Fortitude (the +def stacks).
Aid Self is an interruptable heal, and whilst that can help mitigate all types of damage it adds nothing to your actual defense or damage resistance numbers.
Because my defence is sky high and I'm only taking 10% of inflicted S/L damage I can currently do daft things like tanking two mobs of Crey PPs or a +3 Infernal AV without running Unstoppable. There's simply no way I could do that taking Aid Self over Weave and Tough, I'd simply not be getting enough mitigation.
For a scranker or a scrapper, I'd certainly rather take Aid Self because you're not getting hit for 2k damage at a time. Unfortunately with a survivability-built team tanker it's another story entirely.
HEHEHE thanks for answering just needed a kick start the brain juices and you have given me a couple of things to think about, i have no problem PvE at the moment without aid self or tough, but was lookin for a bit more damage output, in my current build not the 1 above ive gone more PvP (still havent got ACC but ive got tactics) but i just missed my usual tanking style and the manouverbility i used to have.
thanks for your help trying to shoe horn some ideas in !!
Ahh just worked out a great build had a closer look and had forgot taunt back to the drawing board (i wondered how i fit it all in , at least i noticed before i respec)
Heh! Keep at it, took about a week working on Hero Builder till I was happy with my tanker's build...
My view on "Tough" and "Weave" is that the higher you can push your defense/resistance numbers to their respective caps the better. Reason being that a further buff can then mean the difference between getting hit for 50% of what you were before (getting +10% res when at 80%) to getting hit for 90% of what you were before (getting +10% res when at 0%).
I'd probably have taken Aid Self if I wanted to PvP my Tank much though... there's not much point in hitting your resistance cap when 3 ATs can bypass your armor with Criticals/Unresisted Damage/Assassin Strikes!
yeh was thinking along them lines the problem is i dont want to gimp my build PvP only, i like an AoE attack to grab aggro but i would never have a ranged attack in PvE.
I have only played through a couple of mishes with the build ive got now so i will wait to see how i feel. thanks for your comments 
After living with a dodgy build for a while (scobatics cough cough) and going a bit mad with my free respec (putting in SS on my main badge hunter, leaderhip pool)
Ive decided to get dipstar back doing what he does best any comments?
