I made a bow for a customer and it is 52#... He is shooting 410gr. arrows with it, which makes it just under 8 GPP... It is a R/D bow... It has very good performance and the arrows are coming out of there over 200 fps... Should I be concerned at these higher speeds and arrow weight?? Should I tell him to go to a heavier arrow weight to prolong the life of the bow?? I would think that at such high speeds there will be more stress on the limbs... What is your feelings or experience on this??

You just need to recommend a Standard of 9/10 grains per pound.
Some people drive the speed limit and some people don't.

I personally don't worry about arrow weight on glass or glass carbon bows , have shot some light arrows out of my bows particularly out of one of my 56lb 64" FHLB I have got some crazy speeds built the bow to shoot heavy arrows but shoots light arrows better go figure ! I think glass bows can take some light dry fire speeds but at 410 grain it's not that light of course it would depend on the design but I think your fine.

Rich, I'd say it's all dependent on your comfortability on arrow weight with your bows but if you don't set a limit and for whatever reason there is a failure the customer has every right to blame it on craftsmanship or material failure rather than their approach to taking care of the bow. Just my two cents.

I'd go with Mad Max recommendation.

Speed freak. Tell him to get help ;)

Tell them no less that 8 GPP. for his safety and your warranty. If hot rod anything it dont last as long and could blow up.
-
If it blows they will probably insist they followed your guidelines! :(

It is kinda hard to prove anything unless you see it in person. all you can hope for is it dont blow in the warranty period.
