Default 15/43 or 16/45 on SV650?

I find the gears on my SV650 slightly short for our roads. We don't have that many twisties. It is more like long sweeping curves at 50/60 mph and highway ridding.

I am thinking on changing either the front sproket (1 up) or the rear one (2 down).

The quesion is, has anyone done it? Is there a mathematical formula that tells you what it should be? I want to know how much more top speed I would get on each gear, focusing on 1st, 2nd and 3rd. I do not want to end ridding the clutch in slow moving traffic because the gears end being to long.

The final ratio would be 2.81 with the 16/45 or 2.87 with the 15/43. The standard version (mine) comes with 3.00 and the S version with 2.93.

Thoughts?
