Line 6 Pod Farm Vs. Guitar Rig 4

I own a Line 6 UX2 USB interface with matching Pod Farm guitar tone software. I know the majority of virtual software users use Guitar Rig 4, including instructors on GMC. I have been considering selling my Line 6 package on consignment at my music shop to get a Guitar Rig 4. What do some of you guys think about Guitar Rig 4 (or Pod Farm)? Do you think it is worth the trouble?

Also, The only full version of guitar rig 4 I can find comes with an unnecessary controller pedal that raises the price. Does anyone know where I can find guitar rig 4 as just a standalone software, without extra price-raisers?

Thanks!

Left Forearm Problems

Hey everybody. I'm having some problems with my left forearm, and I believe it is from excess playing of guitar. I have been playing a lot more than usual for the past few weeks, and during my practice the top of my forearm on the fret hand will numb up, and afterwards may feel stiff. I do stretch and warm up always before I play. I am left handed, but I play right handed guitars. This worries me because my dad has always had trouble with these same problems from typing. I really don't want it to develop into something serious like tendinitis or carpel tunnel. Has anyone else had these problems, and if so how did you fix it?

Thanks

What's Up

Hey everybody my name is Robert. I have been playing guitar for almost 3 years and have allowed music to become my serious hobby and dream. I am greatly influenced by all the usuals, Vai, Satriani, Petrucci, the list goes on. I am also inspired by these guitarists commitment when they were my age (Vai played 9-15 hours a day when he was a teenager ). I hope to someday be a working guitarist in any way, maybe even an instructor on GMC (some day ). I have known about this website, but only recently joined. I love it becuase it allows both beginners and advanced players an opportunity to advance their skill, with easy to use lessons. I am looking forward to being a part of this awesome internet community.
