Stock oil pan and HV oil pump?

So I changed my mind on the pan...again lol. I ended up going with a milodon 7 quart pan.

This is it. http://www.summitracing.com/int/parts/mil-30941

This pan has baffles in it, and on milodons website it says that a windage tray wont fit, but I phoned and they verified that the new ones can fit one.

I think I may have found a windage tray, new isn't happening around here for whatever reason, so I found a good used one. Also is a 340 and a 360 windage tray the same?

Would I see any real benefit by adding one to this pan?
