Protostar curved secondary holders

Hi all,
I'm looking for opinions and user reports of the Protostar curved vane
secondary holders. I'm building an 8" f/6 with a round fiberglass tube and
a wall thickness of 1/8".

I have used a Protostar 3-vane spider in the past and would definitely use
one again based on it's quality and ability to hold collimation even after
years of transporting the scope.

I've been out of the ATM hobby since these curved vane holders came onto the
market so any info would be appreciated.
