I use a Destroyer, 2 champion one is 167 grams other is 170 grams as looking at the Star there were confusing as one was big dome the other was low dome, i found the Champion are more low dome and use less power to get going but I can barely use that. I draw the line at slower speed 12 discs for me. Thinking about it I should be using a speed 11 disc or possibly a neutral flight 12 at most.
I also have thought about getting a Archon to use as a faster Valkyrie. I just do not have the power for the speed 12 discs and I throw a Valkyrie low so I can throw a Valkyrie into the wind. I bet I could do the same with a Archon.
I am 107-110 pounds and 110 pounds only on a hevy day then I am 5 foot S inches, crappy arm span that is smaller then it should be. So I am even smaller then you. Yes that small. I also know a player that does not use a high speed driver as he finds the discs impossible to control, his fastest disc is a speed 11 Wraith, at least it used to be.
