Hey man,
I've still got a little more work to do on the site, I haven't got the full Filco mod kits with the 2 cables online yet.
Well spotted on the lack of double sleeving, of course I can still do this. I will make the changes tonight.
In regards to the change in connection, I have found the female USB A is a much stronger/ solid connection than the Mini USB (which I had to use a Micro USB connector for due to the size of the female connector) and had to file down the connector.
You are more than welcome to order the kit with a Mini USB, however, I would recommend the new style, its a little bulkier, but much stronger.
Cheers,
James
