No the 3 Excals are recurve. The Maxpoint and the Browning are wheels. I haven't shot them enough to stretch strings or see any difference in them yet. Give me some time! No on the chrony. I can tell pretty much they're all impacting about the same and dropping very close out to 40 yds. 1 came with a Simmons scope and the lines are too far apart for the Excals. The Browning has a Horton scope on it and I have the same problem. 20 and 30 are ok but 40 puts the impact way too high.
I'm shooting 18" bolts out of the 2 bows with wheels and also the Vixen. The others are 20" bolts. The Exomax is faster but at hunting ranges there isn't that much advantage. I feel the recurve ones are slightly more accurate. Same as a longer axle to axle compound is I guess. Still I've managed to tear up some bolts with the Maxpoint.
