The question will be what should follow the Filly, a artisan or a multi-sided paddle with pastes?
You are going cheap(er), but workable with the Filly. Good strategy. My recommendation is that when you branch out beyond the Filly, follow the same strategy for awhile... don't spend much, and find out what you like.
At the beginning of this thread especially, there was a difference of opinion. There are so many ways to get the job done. And, undoubtedly, balsa (and other equipment directions) is not for everyone.
