I believe that Larry does a great job creating relationships with the players of Loka. He has also hosted some great events to really demonstrate how fun and non-toxic the Loka community can be. I think he is the perfect candidate for Slicer.
Can't say I've seen someone nominated for Slicer and applying for Sentry in the same month, but I would agree with Jake's nomiation. I think Larry would make for a good Slicer. I'm still a bit torn on the Sentry side of things, mostly because I think in the future Larry could be a good addition to the team, I'm just unsure if he has the experience on Loka that is needed to be a Sentry.
