Newcomers to the sport of sporting clays are better off concentrating on technique rather than being obsessed with swapping choke tubes between stations. This is because the majority of misses will be due to poor form and loss of focus, rather than pattern density. Beginners should make hitting easy to moderately difficult targets within 30 yards their priority. So going with either skeet or IC chokes is the best move. As shooters become more proficient and want to get better results and feedback on longer targets, adding a light modified or modified choke to mix can be smart. Go with chokes tighter than these only when shooting targets at extreme ranges.
