I use the Gator flow thru spinner on my 200 sold by F3A Unlimited, it has a lightened back plate:- https://www.f3aunlimited.com/gator-spinner-82mm-red.

However, be careful on over tightening on spinner with a lightened plate, may cause warping. If the prop is slipping, just put two spacers made out of sand paper - one between the drive washer & the back plate, & the other one between the front of the back plate & the prop - that should solve the problem.
