Will be purchasing an Excalibur Phoenix.

I think I will start with a 400 gr arrow and see how that works. (300 gr arrow and 100 gr broadhead). Thanks for the advice.

Next question, sorry for the ignorance. Was at basspro today hoping they would have a phoenix to try, but they only had an Equinox. However, looking at some Excalibur arrows, I guess they come with what you call the "flat" nock? Nothing back that looks like a nock to me. Are they used like that or do you have to add a nock? Other brands had the "half moon" nock. To me that just looked more mechanically sound. Your opinions?

thanks again from an Xbow newby.
