I have been using it for some time,in the process of trying it out I have come to the conclusion that 2 x 50 gr sticks shoot the same as 100 gr FFloose if you compress it slightly the same for 150.
The one thing to watch for is that it is easy to get consistancy with the sticks while you have to keep your compression the same with loose.
If you don't compress the volicity drops according to my chrony.
I don't have the same luck with 3F that Cayauqad does it work up to 100 or 110 then my groups open up; with FFI can go up to about 140 before they start to open a little. Each gun is as different as people are so there are things that you can only find out by trial and error. Lee
