cable and interconnect advice?

Agree with tooblue, as your first choice should be AZ cables, and IMHO, the only choice. The speakers are voiced with AZ cables. Also, they are wired internally with AZ cable, so why not have uniformity from the amp output all the way to each driver in the cabinet.

" I will probly biwire from my amp to the single post on speakers if getting them made .. My amp is set up for it "

That is unnecessary, the 2 connections on the amp are just multiple connections on the same output. They are there to use 2 separate cables to a biwire speaker. Spending extra money for this is useless. Use that extra money to just buy a better single connection cable. And again, if you want to get the best sound from your AZ speakers, use AZ cables. Years ago, I tried many cables on a pair of JM Reynaud speakers. Then I just happen to get an opportunity to buy some JM Reynaud cables. Sounded much better than anything I tried, at 1/10 of the price of the most expensive I had used. Never had a desire to change again.

Sorry stringreen, he is not talking about a Shotgun configuration, as that would require a biwire connection at the speaker. His speakers have only one set of connections.

oleschool. I am recently retired, but worked 25 years in the high end audio/video industry. I can't begin to count the experiences and conversations I have had with many well respected people in the industry, Nelson Pass and David Wilson being two of them. Also studied electronics in school and did electronics repair in service. I still say a double connection at the amp end is a useless expense, and to just look at it technically, that double connection will not have an easier flow out as you say. There will not be any increase in flow compared to one connection. It will just split going through 2 connections instead of one, and there is less chance of signal degradation with one connection as opposed to multiple connections. Now it's an entirely different scenario with a biwire speaker, but none of those factors are relevant to your situation.

Ok, stringreen, Shotgun means two separate runs of wire. Over the years the term has been used quite loosely, and I don’t see the need to beat that dead horse. Unless I am not understanding oleschool correctly, he is talking about having a set of cables made that will be a single cable with one set of connections on the speaker end, and split on the amp end with two sets of connections. In that case, it is useless. Now, if he is talking about two separate runs of cable that are connected together at the speaker end only, then I agree with you that it could sound better, however from a practical sense, he could just get the two runs of cable, and stack the connections at the speaker. But I also agree with the comment made to me by a highly respected amplifier designer, just get a better single cable as opposed to splitting the funds for two cables. As always, ymmv.

oleschool, with Mr Lee offering you a good deal and buying those AZ mid level cables, you could just sell them in a year and buy a better pair from him. Used AZ cables usually sell easily. Tara Labs makes great cables, but you must keep in mind system synergy and AZ cables are the best match for your speakers.
