You're welcome / but as you know, none of this came easy to me either ...until I made friends with a couple of skeet shooters that really understood "Fit" ...and I started fine tuning all this stuff.
Honestly, I'd suggest you try and find someone at your club with a Browning Lightning model / there should be a lot of them around ....and see how it shoots for you / take it to the pattern board if you can ....and test it. Pay for the guys rounds and shells for the day / or something ... and see what you can learn. ( If you were in my area, you could shoot mine at no cost ..and see if it really fits )...
These are the Citori XS Skeet models that I shoot most of the time.

They have a lot more adjustability than the Lightning .......but here is the Lightning model I bought new in 1988 - still a solid gun...

I'm a Browning guy ....but I don't know that you can make a bad choice / as long as the gun fits you....that's really the key..
