i did have both back in the day. I would proberly say the RXS300 has the strongest cover of the 2. I can still remember how they were drilled and the Apogee was drilled way stronger than the RXS. Didnt use dual angle at the time but pin distance was 6 1/4 for the RXS pin left of middle finger and mb just right of thumb and the Apogee was at 4½ pin above ring and mb just right of thumb. both was medium balls at best, i remember the Apogee didnt really make a turn where the RXS just kept going.
