Are you throwing a high arcing shot, or a low line drive?
I think Scott asked the most important question. What do you want it to do? Both the tomahawk and thumber are shots that can do a number of different things depending on disc stability and speed and how you throw it.
In my experience throwing a lot of thumbers, I find the more overstable you throw the less turn and more distance you get.
I throw a glow whippet x for distance, around 300ft, it turns slightly and finishes a little right of the line it was thrown on. If I throw a beat up star TL about the same power it travels 200ft, makes a much more drastic turn and finishes way right of the line it was thrown on.
The best thing to do would be to go out in a field and throw everything you have in the bag and see what it does. Then go home and ice your shoulder down.
