I use the rotax racing retainers. Work fine for me

IMO The complete riva kit is best, it's properly engineered with uprated springs and is a complete solution.
If you only want to change the retainer or you can only change them because of rules the Les Cooke's are best, they have been run upto 8800, not sure how long I would want to run that way on stock springs tho.
