Has anyone tried any of these??

I have a deep pocket in an aluminum part (4.2") and I'm currently roughing it with a 1", 2 flute Ingersoll Hi-Pos Alu. I use a shorter tool to reach what I can, then move to a longer tool. Unfortunately, I had to reduce the cutting parameters pretty drastically because of the length. I think that feed mill might be a better solution, IF it can do what they say it can.
