I got some carbon express 250 and 350 hunter large dia. I shoot radial x 100. How much will it change point of impact and will this be better than the 100s? Any help would be greatfull. Im shooting a black bear @ 52# with a 32in draw. Im 6' with long arms.

Dont know the answer to your question, but have a comment, I am also 6 foot tall have longer arms too, znd used to shoot 32 inch length, but have changed to a shorter draw (29inch) a few years back as advised, and it really help me shoot 100 times better, way more accurate.

I would say you would get a 2 inch drop or more at 20 yards . also the 350's are not the appropriate spine for that lbs. if you have them already then shoot them and find out

Pay real close attention to what mbruizer is saying. No matter about your height, but to shoot a 32" draw your wingspan would need to be around 80". So in other words your arms would have to be long---real long.

Now about the arrows. RadialX 100 is way way underspined for your setup. Looking at the PSE chart you should be shooting a RadialX 300.

Checking a CX chart you're in either/or land with the Carbon Express. Probably the 250 would work best, but 350 might work, but be a little on the stiff side. You'll have to try them both and see what works well with broadheads if you plan on hunting with the setup.

Now all this taken into consideration you can bet you'll see a change in POI by changing arrows. But then you're going to need to tune for whichever arrow you choose and then resight the bow. I guess that's why sights are made to be adjustable, wouldn't you say?
