Hi All, I have a couple FF II and EI's, but need a scope for a new Kimber .243. Is there a difference in the glass quality between a FF II and the new FF IV and is there an upgrade in glass going to the Signature line. Camera Land has some nice prices on these and Meopro (I know Meopro is better, I have 3). Thanks for any insight, Y'all have a MERRY CHRISTMAS and be safe! I did take a 9 point last weekend with my 7mm-08
