I have used a freak barrel kit on my ion and this compares greatly with it and performs just as well if not better.
I use a Smart Parts Ion
Freak Barrel Kit
New Designs Trigger
It is very accurate and effective, quite light also.
None, i broke a ball and it shot through it amazingly not losing any accuracy.
This is a great product that is very effective and should be used with an ion. I loved it and was impressed because I haven't been particularly impressed with CP products lately. I thought it was amazing and recommend. GREAT DEAL!!! Amazing Accuracy and weightlessness. I am a veteran player and I think that you should look in to this barrel to improve both your skills and your markers.
