What type clays you intend to shoot...I personally find the 20 s to recoil as much or more than 12.. Mainly due to the lighter weight of the 20 ..I shoot a browning ultra xs skeet for most things except trap...it is a dream to shoot with the ported barrels and the whole gun design....same loads in a field citori feel way stiffer....most clay shooting can be done with a 410 if your good enough....bigger gauge just gives a bigger margin of error....
Odvusly with your shoulder issue maybe a 12 with 20 ga tubes would be an option.to get the weight up some....or one of those mucury things in the butt stock...
