Shooting a broad range of spines.

[high mountain]

Would like to get your opinion of this arrow question.

Shooting a Quinn longhorn classic. 50# at 28 , 60 inch take down recurve. I pull 28 1/2. Actual weight is around 52 53 # at my draw. Fastflight string(I think it may be a flemish twist?)
Elevated bear weatherrest.

Two spines of arrows shoot great from this bow.
Hunters arrows from 3 rivers, spined 65-70 pounds with 125 WW. Cut to 28 1/2 inch.
These POC fly great, perfect arrow flight.

Easton aluminums XX75 2216 With 100 grain adaptors and 125 grain tips. These also fly awesome..although are a bit heavy for my tastes, and I dont care for the trajectory.
Im guessing the heavy point brings the spine down close to the cedars.

Problem is..I have some lighter spined arrows that I would like to use, since I hate the fact that they just lay around and are kind of useless to me if I cant shoot them.

3 rivers hunters arrows..spined 60-65
And Some Blackhawk vapor carbon 3000. Side says 45/60.
Both these arrows refuse to come off the rest cleanly. I get a heavy left/up kick with both of these...and I guess its because theyre too light?
I can tip both of these with the lightest tips I have (bear green heads @ 117 grains)...and they still fly erratically.
Im pretty sure theres not much I can do..but I was hoping since I have an elevated rest, I could tune these lighter arrows in, but so far no luck.
Maybe there is something Im overlooking..but I thought elevated rests were more forgiving of spine.

I cant get the 65-70 to come off the shelf cleanly either...they all act weak without the elevated rest.
Does this make sense?

All of these arrows are 28 1/2...and I usually pull untill my arrow touches the shelf, making sure Im at full draw.
Thoughts?
