Anybody use tungsten/lead tape?

I played with a guy the other day who had been sent a series of cosmetically defective paddles by Viking, which kindly let him keep them rather than returning. As an experiment, he modified each with weighted lead tape to see the impact, and found it significantly impacted the feel of the paddle, sometimes positively.

I tried this last night with some tungsten tape in the nine o'clock and three o'clock positions, and it felt like the sweet spot on my (very light) paddle was a bit wider and volleys were a bit more solid.

Curious if others have experimented with this?
