Best rack for camper shell? Need one for my RSI Smartcap

I'm going to be ordering an RSI Smartcap tomorrow and was thinking of ordering their rack along with it:

Any other suggestions? It's a big decision so wanted to get feedback from the Taco gods.

 

I’m not sure if the Prinsu cap rack will fit the RSI, but you should look at that too. I’m sure the guys over on the RSI mega thread will know too.

The rsi rack is backordered. We use front runners. Let me know if we can help

 

What size front runner works? Thanks!

 

We have them here
