seeking advice on a new CW double stem

[jason64]

I want to purchase a double stem CW and kind of narrowed my choices to Rattray, Chacom and Stanwell. Out of these, I only had Stanwell in the past and I have no major complaint about that. I have no idea about Rattray and Chacom. What would be your pick? Do you have nay suggestion for a double stem CW besides these?
