Just wondered if anyone had any suggestions on this. I just bought a dozen Ultralight pro series 22's. I shoot at #70 28.5" draw and 29" arrows with an 85 grain tip. They are spined at .300. Do you think they are too stiff with this setup or will I be OK.
If they are too stiff what can I look forward to seeing the arrow do in flight.

They are stiff but shoot well, indoors anyway.

I was shoot them out of my 70 lb Patriot, 29.5" draw - cut to 29" and had them flying real well with 100 grn tips.

You may have to go to a heavier tip - see how they group at longer yardages.

I also have a dozen and shot some out of a 2003 Black Knight (T) @ 60 lbs 29" draw. I paper tuned a bare shaft 29" with a 85 gr. tip, no problem to getting a bullet hole @ 293 fps. Thats as far as Ive taken it but it looks like these shafts will work well even at this lower poundage.

If your screen name implies which bow you are shooting then they may work well with your setup since the ES puts out alot of energy. However, normally I would think that a .300 spine would be too stiff considering your draw length/arrow length. A .340 would probably be the stiffest I would normally recommend with your setup.
