I used fairy-tale Sheva at first, but since I always play as her in the main storyline I prefer a change of scenery, lol. Not to mention (I don't know if anyone else has this problem), as awesome as five gold eggs are - everytime I need to take one, I tend to get hit before she can actually eat it. The time seems alot shorter with the first aid sprays and herbs, but I don't know if it actually is.
I've played Barry a couple of times and he's awesome, I think I just prefer characters are bit speedier. That's one of the reasons I rarely touch heavy-metal Chris (that's the one with the Gatling gun right?).
