Mountain Biking - E-13 DRS or MRP LRP?

I'm looking to get a dual ring chain guide. I've narrowed it down to the two models. I can get the MRP w/ ISCG mounts for $125 and the E-13 is $165 plus $25 for the ISCG plate. Is the E-13 worth the extra $$ over the MRP? All i want it to do is hold the chain on the ring. Nothing else. I also don't want to have to replace the BB. Incase it matters, this is going on a Specialized BigHit Comp.

Usually I would say get the Evil in a second. But having the same bike I would recommend getting something else. It doesn't fit the ICSG mounts properly...you would have to mount behind the flange which also leave a little bit of the bottom roller exposed.

ISCG they say....wtf, shouldnt all iscg mounts be compatible????

It is because of the position of the swingarm in relation to how the boomerang fits the bike.

Is this with all Specialized or jut the Big Hits???

I'm in the same boat. MRP or Evil. If I could get the red bash guard it would be a no-brainer and EVIL all the way. The ones I've tried and from the people I've spoken with claim the EVIL's work great.

However, $65 is $65! You know how many six-packs that buys???

Not sure about the sx. I would email evil. Either will work but from what I can see, it leaves the lower roller slightly exposed. The MRP does not. I still went with the evil...thats how concerend I was by the exposure.
