Help with Choosing a Bobro

[Glen9010]

Just received my Sightron SIII 3.5-10x44 and am now searching for a nice mount. Looked at LaRue, ADM and Bobro. After looking at and reading about all of them, I think I like the Bobro the best. Very clean design and solid mount. My question is, which Bobro should I go with? The standard length, model B03-200-300-R1, or the extended, model B03-202-300-R5? This will be going on my Sig (http://www.sigsauer.com/CatalogProductDetails/sigm400-enhanced-fde-ca-model.aspx). Have a look and let me know your thoughts. Due to the cost of the nicer mounts, I only want to do this once.

Thanks for the input!

If you shoot NTCH you usually need the extended mounts. Bobro's won't mount flush with the end of the upper receiver and the mount base is relatively small, so its easier to move back then move forward.
