Different length of arrow for different bows?

[Rossco7002]

I'm in the process of setting up arrows for a second toelke whip I've picked up. My first one shoots a 500 with a lot of weight up at the front but I wanna set my new rig up with a lighter gpp, 125gr points and a 600 spine (so I can buy over the counter broadheads locally). This set up would result in my new arrows being longer than my current ones by approx 1/2 inch.

My question is:

As an instinctive (split finger) shooter is the variation in arrow length likely to through me off when switching from bow to bow (I wanna use them interchangeably)? I make no conscious note of my arrows position before releasing my shot.

Opinions/experiences of a similar nature greatly appreciated.

Cheers,
Rosco

There will be significant differences between the two setups that you'll have to get used to, as trajectories, etc., will be different.  I think any difference due to the arrow length will be lost in these other differences.

There will be a difference in sight picture, whether you pay conscious attention to it or not.  This probably would not affect your shooting until the arrow point comes up close to your point of impact.  At normal instinctive distances of less than 30 yards, the arrow point is enough below the target that a half inch more or less of arrow length will probably not be noticed.

Hey McDave,

there'd only be 1-2 gpp difference in the arrows so trajectory differences should be negligable. This is my 3rd season with a longbow - I don't shoot on game beyond 20 yds and this'll be my fist season going beyond 15 so I just want to be able to use whichever bow grabs my attention that day rather than stick with one all season.

I like to have a lot of different bows, and shoot all of them whenever I feel like it.  They say I'll never be as good a shot as I would if I stuck with one bow, but that is part of the fun of it for me.  One advantage is that I can pick up anyone's bow and shoot it pretty well, since I'm used to shooting different bows anyway.
