I had the same dilemma btwn the Lynx and the Incubator for my WBRR. I ended up getting the Incubator because it has 900 fil vs 850 for the Lynx. They were roughly the same price. Also, 900 fil can be hard to come by at times at a reasonable price so I wanted to get one before there was a run/shortage.

I emailed HG and they told me they had a RR in the shop and verified that it fit. If you have any questions, I'd email the company. They are really nice people - both Warbonnet and HG.
