OK, I ended up trying just about every combo on 6 different bows and I'll be staying with my woodies, for the most part. However, Thanks to Rob's GT 5575's and Brock's thoughtful addition of the 250gr field tips, I ended up buying some carbons for my Whisperstik Mojo 56" recurve. I had an early Father's Day gift card from Cabela's thanks to the in-laws, but they didn't have Gold TIps fletched with feathers. Turns out their Stalker Extreme arrows were available with feathers and were a dead match for the GT's in both deflection and weight. Here's a group shot from 20yds with the Cabela's carbons set up with 250gr tips. It's hard to see, but there's 3 arrows in this picture.
I'm not sure what the FOC is, but it's way forward. Total arrow weight is 540gr.
The arrows will be headed out to Dagwood 64 tomorrow. Thanks for the chance to try these out and learn a bit about carbons.
