WyoBadger, I have a Dixon as well as a Burke Viper and an older Burke EZ model low D here. If you can play the Dixon, the Viper will not be much of a change for your grip. The hole sizing is not radically different. I am assuming LH, left hand, is on top. Without getting the digital calipers out the obvious differences are these. LH1 and LH3 are a smaller on the Dixon. RH1 is smaller on the Viper and RH3 is smaller on the Dixon. I should add that the hole size on the Viper is quite managable and most any adult hand should cover the holes easily.
The spacing between holes is again reasonably close in both makers whistles. So you won’t have much of a stretch to move to a Viper. I measured the stretch for each hand as the distance from the top edge of the top hole to the botton edge of the lowest hole for each hand. On the Dixon the LH stretch is approximately 80mm and on the Viper it is approximately 83mm - just a scoosh more. The right hand stretch on the Dixon is about 78mm and the Viper measures about 83mm again. Not a lot of difference. The Burke EZ differs from the Viper in the size and placement of the lowest hole, RH3. The EZ right hand stretch measures about 79mm and that lowest hole is closer in size to that hole on the Dixon.
And consider that the lowest hole on the Burke Viper can be rotated which mitgates any issue on the right hand stretch quite a bit more.
Hope that helps.
