what would a good collective for black shark look like?? the only one i have any experience with is the blackhawks.
Difficult question to answer. Basically, ANY collective that worked would be a good collective.
As you know there have been quite a few people there crazy enough - and I am one that is contemplating following in their footsteps!

- to invest time and money into making their custom controllers, in this case collectives, specifically. The first one that comes to mind is GrizzlyT's RAH-66 Comanche simpit, which needs no introduction anymore.
I just did a quick search on the Blackhawks' cockpit, and its collective looks worthy enough of me!

What is interesting is the implementation of different people's ideas.
In the end, there is no such thing as THE ideal collective. A lot people have come up with very sound, yet different solutions to their problems. While there are quite a number of HOTAS setups out there (which can be flown with different sims) there are yet to be any affordable and advanced collective sticks. And simmers out there have done a great job trying to find their own solutions.
Now, don't forget, no matter how much love, passion or madness one puts into such a project one still has to make sure it is compatible with future helo sims.
So, to me an authentic replica of a cockpit will not really cut it. DCS have announced they would - at a much later date - release an Apache helo, just as they announced the A-10. Can you picture yourself flying the Apache with a cockpit replica of the BS?

At best, it will be an incentive for such passionate simmers to create a new simpit.
