I tried a few recently and really found it hard to adjust, Especially on a 5 string! All that meat behind the thicker strings just made the neck feel HUGE!
Personally, i'm not a fan at all. [/quote]
If it felt huge, it was huge I expect but not all asymmetrical necks are.
My MTD 535 has one that is quite shallow and feels great to me. I don't really notice the asymmetric part whilst playing, it just feels good to me. I certainly wouldn't call it meaty.
Having said that, I have owned & played many basses without this feature & I have never wished for this as the missing ingredient.
All I am really saying to the OP is that necks are very personal like most tactile things. I think that you need to ask Ruach if you can play some of their basses with different neck profiles to see what you prefer or take them in your favourite neck as a template/starting point.
