First I would change the string and cable get one from gibblet here on the forums as I have heard nothing but good about them but have never used one YET.

Spott Hogg sights are about the best you can get.

Muzzy Zero Effect or GFK Infiniti are 2 of the best rests you can get.

Fletcher Tru Peep or Speciality Archery Hooded Ball peep are about the best peeps you can get.

Stealth stabilizers are good but so are Doinker,Simms,Sorotek and a few others.Really boils down to personal preference.

I am sure your going to get a lot of different opinions but they are mine and I am sticking to them
