Since you shot some of Tim's 3 pc treesticks, the simplest answers to your questions about speed and how easy to silence his recurves would be:
1. his 3 pc recurves seem to be a tiny bit faster than his 3 pc treesticks.
2. his 3 pc longbows seem to be a tiny bit easier to silence than his treesticks.
I'm pretty much a chronic bowaholic and have traded a bunch of almost every kind of recurve and longbow that's out there.
My go-to bow is a fine shooting little 56" 3 pc recurve that draws 53# @ 28" but, like most of his bows, is dead quiet, is not spine-picky, and draws like it's 3 or 4 pounds lighter than it is.
And when I do my part, it shoots like it's part of me.
