Did you not buy a package that came with arrows? Just asking, no biggie. You will want to make sure you follow TP's lightest recommended arrow/component weight, regardless of what type arrows and heads you wind up with. Do not buy or build arrows that are under that weight, as you risk damaging your bow and injuring yourself. I chose the Evo X Center Punch arrows with lighted Alpha nocks. I don't think you are limited to Alpha nocks ONLY like I am, so you will have some choices as far as lighted nocks go. Lumenocks or Firenocks seem to be the most popular. You MAY want to consider using Alpha nocks though, being as they are supposed to help alleviate the contact issues between nock and serving that arise from the newer ultra narrow crossbows. In other words, they keep contact with the string for a longer period of time down the rail, thus providing better, more consistent accuracy. They are also less likely to have the string ride under/over the nock during a shot, which for all intents and purposes, creates erratic accuracy and could potentially harm your bow. As for broadheads, there are lots of quality ones to choose from. I personally choose 100 grain heads. but some like 125 grains. Popular and good performing heads are NAP Spitfires, TruGlo Titanium X, Thorn, Grim Reapers, SEVR, Dead Ringer X Nasty, Etc. Just make sure you get the crossbow version of whatever heads you wind up choosing. It doesn't take a ton of KE to efficiently kill deer, but you can always add weight to your arrows in any number of ways, from inserts to vanes, to nocks, and obviously the broadhead.
