Default Virga, rain, cloudsuck - how close do you get?

Typing this with my fireproof suit on...last weekend I tried to duck between two rainy cumulus clouds on my glide back to home base. As I went through the gap it became filled with virga and I was sucked rapidly upwards, probably would have been about 10m/s if I had not had the nose well down. This was not tranquil, but not terrifying either (I was about 3000 ft below cloudbase) and added some useful height and speed.

So here's the question: would you (do you?) deliberately head into virga if you needed the boost, or is this a truly dumb thing to do? Same for rain clouds (assuming you are in updraft not downdraft zone), how close would you get?

Not looking for legal technicalities here, this was good VFR at all times - just trying to calibrate risk.

Be sure it's virga... https://www.youtube.com/watch?v=ObYRYF3d38Y

I'm kidding, a little bit, but I often find virga that is in sinking air. I
usually find lift in the edges of virga, particularly the downwind side. The lift
has always been weak to moderate - a few knots at best - nothing like you describe.
