Yeah, the newer Cabela's broadheads (FX-3s) look good in the catalogs, but the older FX-3s didn't impress me. The tips were screwed into the ferrule with a short and small diameter shaft. They would bend pretty easily with quartering shots. It's worth taking a look at the newer ones though, $19.00 for 6 broadheads...
I've been shooting 100 grain interlocks lately. Plenty of penetration, strength, and sharpness, even after several shots into 5/8" plywood. Also, $36.00 for 6, that ain't bad either.
