Its been a long time since I've used Spiro Weichs but I am LOVING my spiro solos tuned to orchestra. The sound and feel is extremely even from string to string, they have the growl and sustain often associated with Spiros but with a darker, thumpier more 'classical string pizzed' kinda sound. They SING with the bow and are extremely easy to start arco.Yeah that sounds like what I'm looking for. What about the spiro solo set and tuning it orchestra? It seems that they have really even tension too, but how do they sound vs weichs?
My only qualm is that I hear the G as being noticeably brighter/twangier and feels really thin/wimpy in my RH when pizzed. But this is really more of a personal preference thing.
