i like the wrath over the spyder.
y?
because the spyder has more kick and because of that, it is more difficult to shoot fast. also, the wrath is a hella lot lighter, i would much rather be running around the field w/ less weight. one downside to the wrath is that it does not shoot as quickly w/ an egg as it should, but using a force-feed loader (ie halo b, empire b, quantum loader) u can rip.
U can also get a t-board for the wrath at scenario dreams, which i believe makes the trigger more responsive and gives it unlimited bps(or 36 bps, but find me someone who can shoot that fast...)
IMHO, this is just what i would do, sell your spyder for a nice sum of money, get a halo b and a t-board for your wrath. u will probably have a very nice shooting marker and the nicest wrath on PBF
EDIT: Oh ya, if u do sell the spyder, u should keep the CP reg, the wrath reg is pretty good, but id rather go w/ the CP
