" You really think that the arrow will kill my riser?"

Speaking from personal experience...yes, I do.

" I must have asked everyone who worked in the proshop if they were ok."

Compounds can handle arrows in the 5-7 grains/pound class just fine because of their construction. Machined aluminum, or magnesium, risers are much more durable than wood. I don' t know of a single bowyer who recommends anything lighter than 8 grains/pound...for a reason.

" Does the fact that they are carbon arrows make a difference?"

It' s not the carbon that' s a problem...it' s the light weight itself.

" You really got me worried now."

I didn' t mean too, really. Just trying to avoid one of those " my bow blew up" things. Seriously, get that arrow weight up to at least 8 grains/pound. It may save you a lot of heart-ache.
