Effects Of Arrow Spine
If you shorten your shafts but compensate by going to a different shaft size thus keeping weight the same, would it effect arrow spine?
With all other things being equal ( length, weight, flectching, nock, insert, broadhead ) are there any advantages or disadvantages to using a larger or smaller diameter arrow? Thanks for your input!

Are you using it for 3-d or hunting? I don't know if you mean carbon or aluminum. Perosnally, I would rather have a smaller diameter thicker wall aluminum for hunting. The shaft should be a little heavier, more durable, and should provide for better penetration. For 3-d you would be better off with a larger diameter shaft in order to touch the line more. But don't be fooled into thinking that the same weight shaft will give you the same spine or deflection rating. Take a 2020 aluminum and compare it to a 2613 if you want to see what I mean.

Down side is fletch clearance is harder with small shafts as is putting a helical/offset on them and long fletchs.
I've heard people mention the difficulties with putting on a helical with smaller shafts, but I have not found this to be a problem at all. But maybe you mean the extremes. I have alway had an easier time getting a helical on 22-- then 2613 aluminums, and even most carbon shafts. I have never really tied any of the extremely small shafts though. This would be on a Bitz jig.

when and arrow hits a target (wether it be a deer or a target) the arrow makes a snake motion as it enters what you are shooting. when I mean by snake motion the arrow actually bends... a bigger diameter arrow will make the arrow not bend as much.

Doesn't this snake motion that you are speaking of have more to do with deflection then arrow diamter?
Would a 2512 with a spine of .321 have less snake motion then a 2317 spined at .297 or a 2419 spined at .268?
