I went with Mast, purely because they have been in the VVT game a LOT longer than anybody else. They will cost you more than a TSP, but I felt it was worth it.
As far as the pulley system, I can't help you there.
I would use tsp for the vvt cam. They make more power then the mast cams. Also Holley sells accessory brackets that are reasonably priced.
Good luck
