I'm strongly considering getting a 50 pound max bow to shoot 3d with next year. Will I be able to get an ibo open class arrow down to 250 grains at 26 inch shaft length? I would prefer to shoot Easton Lightspeed 500s, but am thinking I may have to switch over to some GT ultralight 600's. Any opinions?

Rating for rating, the Carbon Tech Cheetah is the lightest shaft I've found out there that is a quality shaft.
Their lowest spined shaft is the 25/50, and would weigh 137.8 grains(@26") with the shaft alone. The UL 600 would be 148.2.
Even the next size stiffer, the 35/60 is still only 158.6 grains.
Its an excellent 3-D shaft, and is also offered in the .001 straightness.
Keep in mind,its a pretty good thing to be light, but its a better thing to be accurate and consistant. The CT Cheetah 3-D's give all of the above.:wink:

Use VaneTec mini-FITA vanes

I think you are prob going to have your work cut out for you. the only thing bad about the ultralights the spine isnt very consistent.

You are just going to have to play with some numbers really. It can be done without much of a problem. I have a buddy that shoots an Apex 7 at 50lbs and a 29" draw with ACEs and he gets over 290 fps. He also has a normal amount of FOC (not sure the exact number but it isn't 7% or anything like that). Also just because you are shooting 50 lbs doesn't mean you will have to shoot a 250 grain arrow to reach 3D speeds. If your draw is 28" depending on the bow you will more than likely have to shoot an arrow the 275-300 grain range.
