I have three bows, each a different style:
Modern recurve- Bear Super Kodiak.
50's style recurve- Mahaska
R/D longbow- Mahaska
They are all in the 40-45 pound weight, so a change in point weight allows most of my arrows to work for any of the three bows.
The only other bow I'd consider adding to the collection would be an ASL with string follow. Don't see too many out there, so not sure that will happen!
So to answer your question, yes I switch out bow styles, sometimes a couple times a weekend.
As I get older, I've eliminated redundancy in my bows (and other weapons), and narrowed it down to my favorites.
