[Compact_Killer]

i am getting a new gun and i want to know what gun is the best for me. I am looking at an autococker 2000 or a shocker 2000 4*4. i am a front/middle player and i want to know the pro's and con's of these guns ( only if you know personaly )!!!!.i would also like any web-sites that could help me with trigger jobs for the cocker or any other sites.
if i got the cocker 2000 i would get:
14 in boomstick
lapco drop foward
68 cu nitro

if i got the shocker 2000 4*4 i would get:
12 in boomstick
20oz anti-sipion
gidgit grip.

thanks
