Hey guys. I've been wondering if anyones picked up the new Kerry busker, and has played a thunderbird before (Ideally of similar key)? They are quite a bit less expensive. I always liked the sound of thunderbirds. The busker sound good in Kerrys new videos. I'm wondering about air use and how hard blowing they are though. They seem like they may be soft blowers, which isnt really my thing. And as a bonus if anyone has played the optima F how does it compare to thunderbird or busker? Because its the D head I'm worried it will be too hard blowing and too loud. But the Optima D is quiet so maybe the F is normal volume. They are all on my list for good F options. Thanks for any info.
