Arthritis drove me from dreads almost 10 years ago, they all turned into OM/000's, and I honestly wouldn't go back if I could, and I owned some great upper end Martin dreads.
You can't go wrong with an 000/OM-18 GE, and my first year OM-18A (pre VTS) has turned into a beast.
If you like Mod V necks a GE or most Authentics have beefy profiles, they punch above their "weight class", happy shopping.....
