Jim, no twist here, except in the strings! I love them old Bears and other makes of that era, as you do! You also said you seen the results of this Tomfoolery, I haven't. But I always feel there has been more abuse to these bows. It's usually from light arrow weight, left standing in a corner, hot car etc. Lack of respect to fine craftsmanship and history!
I recently put a 10 strand D-97 padded loops, flemish on a 45lb @28" Bear Brown Fox recurve my son shoots. Yes, solid fiberglass, thick tips. Shot some 2117, 180gr. tips, WOW, super quite, no hand shock! I would take it hunting for sure. Now would I do it? NO..... Good shootin, Steve.
