I play German. When I was in my late teens it was a HUGELY important topic. Now I could not care less.
The only important thing about bowing is the fact that the more expensive the bow, the easier it is to play. We kid ourselves this is the same with Bass Guitars. That is not true. Any decently set up Bass Guitar will be just fine and dandy. Sure, we all have slightly different preferences, but they are just planks with metal in them. Playing with a really good bow is bonkers. Everything just works. Sadly, when I say a really good bow I mean north of £5K and probably north of £10K. Yes, there are plenty of good bows around for less, but once you have played with a really good one, everthing else is a bit of a let down.
Just for reference, I do not have a really good bow.
