I need a center chin rest.

A nice, low center chin rest. I think that will help with the whole “aiming over the crest of a hill” feeling that I get on my A string.

Update: Just ordered it from JSI, along with a set of replacement strings, what has become my standard set of Corelli Crystals for the A and D, and Obligatos for the G and C. Blends nicely. A full set of Obligatos almost results in two different instruments when going from the G to the D.
