I kept my marker the same and used the stock drive spring for this test. Cyclone was not attached.
Here's my data:
To my surprise, RVA's are quite a bit more adjustable than spring kits. According to previous thought, spring kits were used for big changes and RVA's were used for fine tuning. It seems that RVA's can handle both tasks better. In addition to that, they are infinitely adjustable. However, not all RVA's allow a stock to be attached, so they do have their drawbacks.
