I own an adjustable"high rib" combo, and shoot it quite well. I also own a Pro-rib Ljutic (fixed rib), and shoot it quite well. Both guns are dialed in for me. When I shoot handicap, I add a spacer to the comb and leave the rib alone...changing the rib back and forth is a pain, and, quite frankly, I don't look at the rib when shooting...or try not to. I find that I am shooting and enjoying the Ljutic more and more. Personally, I find the adjustable ribbed gun, for me, is a fad. A taller (Pro rib is 0.70" tall) fixed rib gun is a fine alternative,generally somewhat cheaper and more durable.
