Rook, I got back to shooting after an absence of many decades and decided to "do it right" and took lots of lessons. Orvis at Sandanona and H&H in London and learned the "Churchill" (really a modified Churchill) techniques and have never been sorry.

It looks good! And it works.

If you get a chance take a look at Ken Davies' The Better Shot which is a superb shooting book - very well illustrated and is the modified Churchill method. Orvis' wingshooting book is very good also but has drawings instead of photos. Either will introduce you to the Churchill form and you may just get hooked on short barrels!
