I think they are both good games, ea05 is very realistic but sometimes too boring. I've got RPIC on ps2 and love it. The shot direction is very to good, to the point where I can try hit a gap in the field and go through it. At first bowling was hard and needed a autoplay feature but after a few tests I love bowling. There is a real challenge to get wickets on state level.
With a few more tournaments, domestic and a few little gameplay fixes RPIC/BLIC would be a very good game.
