I did a mix of RPG and hand made bass traps.
The RPG kit uses a different kind of foam, that works as a membrane, having better mid bass responses.
I also did several bass traps. Check Ethan Winer's forums, where he explains how to do a fiberglass/rockwool based bass trap.
I did check Ethan Winer's forums and ended up watching a 15 minute video of an attractive young lady explaining bass traps whilst taking all her clothes off. I'm not too sure I learnt that much but it was 15 minutes well spent. Cheers!
