Interested to know how tall you are, if average 5 10" to 6' I would suggest a lesson with a coach to address how you mount the gun, then a good gun shop should sort you out 👍
When I bought my invictus I tried barbarys demo which was a 30'', I bought a 32" ltd and have to say I didn't notice much difference in handling, mine is a standard flat rib by the way
I have to say I don't notice the bead at all, I only use the mid and front beads to check allinment when pre mounted shooting a trap type target, other than that the barrels are in my prifral vision as I concentrate on the target 👍
