Tim,
I would go with the BAS hands down. This is safety equipment. I've "pull tested" the BAS harness in a 185, and installed them in my airplane the next week. I wouldn't own a Cessna without them.
Advantages of the BAS over ALL other harness systems:
1) BAS is inertial reel. And the reel actually works. This is not the case for many supposed inertial reels I've used in past of brand X.
2) BAS installs the inertial reel up inside the headliner, and the strap slides through a metal flange that attaches to the outside of the headliner. The straps therefore never get crossed up on the reel, the reel never gets dusty, grimy, and therefore non functional, etc, etc.
3) Finally, there have been a NUMBER of shoulder harness failures in Cessna aircraft of harnesses where the reel was simply attached to the FRONT of the front wing spar carry through. ALL other harness systems I've seen attach there. The BAS, on the other hand, attaches to the REAR of the front spar carry through, with a doubler, and the bolts attaching the harness reel go through the spar carry through. Don't know if I described that precisely, but the point is, to rip one of those reels out, you would have to take the entire front spar carry through box out of the roof of the airplane, and if that happened, you'd have more problems than harnesses.
4) Really--there have been a lot of harness failures in Cessnas. I've never heard of a BAS failure. Look at their web site. Look at the pictures. The 185 floatplane on there was mine. There are others that are just unbelievable that anyone could have survived, but the harness system worked.
I have the Utility system, and I like it far better than the seaplane version, which I didn't even like in seaplanes....The utility version is easy to hook up, unhook, and works great.
Don't even think about any harness system in a Cessna except BAS.
