Both are good chokes, but the only way to know what works best in your shotgun with the shells you are using is to try them. I would not be afraid of the less expensive choke from CDNN. Last year, I was able to pick up a full set of factory extended tubes (Ren=mington ProBore) for my gun at $9.99 each. I also have a few higher dollar chokes (Briley and Pure Gold) and the best of the lot for me is the Extended Factory IC choke. CDNN has flat rate shipping, so that $10 choke tube will likely cost you $20 when all is said and done.
