Go with the ELS system, the best one out there. You can't believe how versatile it makes your set-up for different stages. Also go with the Carbon Arms ratchet belt system. Good luck.
I've been using MBX since Adrian started building mags.I"m still running the prototypes I started with. All they do is run and run. Never had a problem. You can"t miss with MBX.
If you have enough acreage build yourself a bay. Make it at least 50yds. long and 25-30yrds wide. That way you can set-up different stages and have enough room to change them as your needs arise. Also make the berms at least 10ft. preferably 12ft. high.
I had not watched the National Felon League all season, started to wane until the pimp Goodell refused to accept the Amvets program ad. I'll never ever watch another game . The only group more hypicritical than the NFL is the Democratic party.
