I've always been partial to the looks and handling of open-top revolvers, and have both an original and reproduction of the London Model 1851 Navy .... but don't shoot 'em much.
Last year, for CAS shooting I picked up a repro Richards Mason conversion in .45 Colt, and had a blast shooting it. Then, just last week I made a deal to buy an "as new, in the box" repro Open Top ..... also in .45 Colt. Don't have the latter in hand yet, but it should be along in a week or two (coming from the other end of the country ....)
At any rate, since I'll now be set up to shoot two "open top" revolvers, I figure its time I joined STORM. Please sign me up!
