Which PLB?

[Sling 2 Pilot]

Ive narrowed my choice down to the ACR Rescue Link+ and the Ocean Signal/ACR PLB-1. Both function identically, the PLB-1 is the smallest PLB, the Rescue Link+ is bigger and also Boyant. By The Way, ACR bought out Ocean Signal and the PLB-1 is still branded by as either the Ocean Signal Rescue Me PLB and as the ACR PLB-1.

I was leaning towards the RL+ for its buoyancy, but the size of the other unit is. Worth the look. Any one have experience with either? This would be in addition to the 406 I’ve got installed in the plane.
