Anyone using a different kind of strut other than factory on the viper

I am using Behotec C50F electric gear along with their C50 Heavy Duty All Terrain struts with swing arms. Also Behotec electric brakes. Gear and struts are built like a tank and mine have over 50 flights on them. My generation 1 brakes were way below standard but the second generation of brakes works perfectly for the Viper.

Thanks iam using the behotec retracts and was wondering if there was a suitable replacement for the struts
