I picked up my first crossbow today, WR Invader. I used to bow hunt but it has been 15 years since.

I am sure a lot of it comes down to personnel preference but I am curious to hear what bolts and broad heads you guys are using? I will be using the Xbow for whitetails in Indiana. Do most of you shoot carbon bolts? What are the pros and cons of carbon vs. aluminum? Also curious if you shoot mechanical of fixed broad heads.

Lastly someone had told me that crossbow bolts lose accuracy after a certain number of shots. I am guessing this would be because of the amount of force the Xbow places on the bolt. Is there a certain number of shots one can expect to get out of a bolt assuming you don't bend it removing it or robin hood it.
Thanks
