I think that is the one I am going with. According to Eastons website I can up my poundage a little if I wanted to with these arrows.

What's the difference between XX78 and XX75? I know the 78 are a little straighter is that it? Thanks!

the 7178 t-9 (xx78) is more durable than the xx75...its a better metal.

also on easton sight they market a target arrow called the x-7 its the same as the superslam only black and they have more (and different)sizes available in that model...

i thought easton was cutting back on there alum arrow sizes....but they have pretty much anything yyou need. the only difference is they are marketing them torwards target shooters.
