I was wondering what arrows i should get for my new bow. should i go with carbon express 250 or 350?

350, definately the 350, and not just one doz, but at least 5 doz. In fact get as many as possible.

Is there a reason i should get 350 over 250?

Well, because its a much larger number. Thats always good, except in blood pressure and gambling debts.

Ok, slick. How about we start with the bow your using, including model and year, draw wieght, draw length and planned heads to use. Then we can tell you more info.

my bow is the 2010 Bear strike, i have a 27inch draw and 60lb draw weight. i want to get the new carbon express mayhem hunter arrows but do i get them in 250 or 350?

i am getting the new carbon express mayhem hunter series and was wondering whether to get 250 or 350? bow is 2010 bear strike, draw length 27in, draw 60lb

I almost choked on my coffee, that was classic!

Back to the question, neither! You need CX 200's.. the others are too stiff for your set up.

But then what if i get my draw weight set to 70lb? will that not affect it?

Then go with the 250's.. I have a lot of different bows, and even some set a longer draw lengh, I buy arrows for each bow. Rarely do I use the same arrow out of two bows because they are not always the same set up. I use different bows for different things.
