I just got a outlaw hen from Lonnie the other day and, going through my strikers it seemed like a Holloran Jatoba sounded the best to me. That said, to be honest, it'll be hard to beat Lonnie's purpleheart striker that he sends with the call.
Another guy who makes a pretty sweet striker that sounds great on Lonnie's glass is a Matt VanCise diamondwood. He'll whip you one up in a day or so...
