Diamonds are still high priced bows, not alot of difference between them & Bowtechs $$ wise. But both are great bows.
If your considering a Hoyt, then why not look into the cheaper Reflex line. Those can be purchased little cheaper than Hoyt, and your still getting alot of Hoyt in them.
But I'd shoot any bow before making any purchase, whether it be store, shop, or catalog.
