Howard, good info.
Just as an FYI,,, I am a big guy 6ft tall 375.... even your size XL was tight around my neck and uncomfortable.
As you pointed out.. the Hans has the high back for rebound protection and that is a good idea,, so since I did not fit in a Hans well, and the Safety Solutions was my choice, I am using and ISP containment seat with a high back head rest (for some bounce back protection)
I do like the Hans and think it is a great choice for most,,, as are many other HNR's...but if the driver is a bigger person or the cage is confining and or the Hans hands up when getting out, or you have an extreme laydown position, the Hans, may not be "as good a match " as some others. They all have there limitations,
It is personal choice combined with fit to your particular application, price should not come into it, as each major HNR mfg has multiple products and price points.
I think this is a great topic as it makes us all think about HNR's...
