I haven't read every post, so I may be repeating what someone else said.
but I think the reason for all the Hill style bows and threads is likely compared to the old saying: "What goes around comes around".
I remember when I first got into traditional bows, I had several recurves and my friends did as well. But we all desired a longbow. And at that time, it was just longbow...... not Hill style, just longbow.
So we got one. The as time goes on, we got into takedown recurves, then the metal riser recurve craze and ILF limbs and carbon foam innerds and all that stuff.
But now, after I experienced all the bells and whistles, I'm wanting to just go back to something simple. I am at the point that I just want simple, dependable, and something classic looking. Hard to beat a Hill style bow for those qualities.
