RJ Daley,
I think the shrub is acceptable, in small doses. It just can not be fun to hit into that shrub, because there is no chance for a recovery shot. I like allowing recovery shots because the player must make judgements about how aggressive or conservative to be on the recovery, and make these decisions in a semi-flustered state, which requires poise.
Along the lines of keeping the bunkers rustic, what effect is there on a player's ability to extract themselves from the bunker grounding vs. not grounding the club? Is bunker play appreciably better if you ground the club? If not, why the rule, why not do away with it to give a clear, simple solution to those whom wish to mix their bunkers between more clean edged, and more rustic on the same course.
