I tried alsorts with my baritone low D, high D, low G. high G. I didn't really like anything. Eventually I put Worth concert strings on my and tuned it up to high G, C tuning. It's been like that for 9 months now with no problems. It's a Clearwater roundback bari (like the Ohana roundback concert only a bari).
It sounds great now - really great. I realised at the time that I was pushing it tension wise but it's a fairly cheap instrument so I thought I'd risk it. I don't think I'd do the same with an expensive one.
