Surely you jest...perhaps you mean it will come down less quickly upside down than a GL will?
You're right on about the speed though. A GL becomes useless expodentially as the windspeed increases whereas the Spirit will penetrate much easier.
A Kestral will have even better penetration due to a thinner section (S3021 I believe) but for the price it's hard to beat the Spirit as a poly 2m.
