I know a lot of you have seen many of my posts and are probably getting sick of me asking questions, I don't have money easily accessible so if i do some thing i want to be the best and know 100% that stock the rig will hold up to any type of abuse anyone can put to it. I want to buy one rig and one rig only and i really hope that from what you guys can help me out with, that it would be the best.

Thanks
