Best I've seen with mine is 106...Stock 260 and a 25lb bag that I move around depending on what or who is in the boat with me. By myself it will either go to the passenger side or the middle depending on whether or not a cooler is in the back passenger compartment.
I also turned my slide to the side, so it slides left/right rather than forward/aft. This definitely helps. It's also helps to have long legs. Lol...
Best prop is a 28" Hoss Triton...I've yet to run a 30 on my boat, but I really don't see much more in it. Maybe 107, but I've really quit caring about it...I've seen 105-106 plenty of times and anyone claiming faster with the same setup would have to show me.
I will say this...without some sort of ballast, the boat will never fly straight. I've tried it more than once, and it's virtually impossible. Even in short bursts with a drag race setup and seat slid towards the middle, it still won't do it.
Good luck with it!
