12 total 7 recurves and 5 longbows spanning about 6 decades. Think I bought my first recurve from K-Mart in the 70s a Pearson

Enough to start an archery shop. In other words, I don't know.

Two. It's the same model and at the same draw weight. My oldest is a one piece longbow and I love it but it's difficult to travel with so I had a 2-piece version made to make travels more convenient. If I had to keep one of the two I'd keep the two piece version solely for the improved convenience when traveling but in actual use I can't tell any functional difference between the two. I'll die with my two Sarells Sierra longbows in my collection and at least as of now I am not planning to buy another bow.
