The only problem with the ions were the solenoid. At high ROF it couldn't quite keep up velocity wise so it would drop like 10-20 fps at a high rof. The only way you could notice it was if you shot it at its close to max range, which you would never really do in speedball.
Iv'e noticed that at about 25bps+ so...... lol it wont be a problem.
Boris- heavy is good, heavy is reliable, if it does not work you can hit them with it.
