RE: What are you using for a test stand?
A Black and Decker Workmate is a very good test stand..I took the stock top off and replaced it with a couple 2x10s..I run 3W 150s on it with no problem...Put the vertical piece on the same side as the step...It folds down for storage or transportation..I'm on the second one in 18 years, they eventually get loose from vibration...
