Kyle... Being from the midwest and being an old friend of Earl Hoyt, I've used all the generations of the Flex Rest.
It's evolution is a direct result of the hard plastic vanes used in competition during the 60's.
They would often explode when they contacted the arrow plate during a bad release.
The soft rest and plate of the Flex Rest totally eliminated the problem of breaking vanes.
A side benefit of the Flex Rest is that it's a very forgiving rest which greatly simplified bow/arrow tuning.
They are a great rest and I'd just go ahead and use the Neet product. It seems to be more heavy duty and works just like the old plastic model.
