I actually use 16 pound bowling balls lol. Have around 35 or 40 of them. All brands and types from reactive to urethane. Big fan right now of the Reality and the Venom. Average around 225 in many leagues and tourney's. Am also a PBA pro although not an elite one. Most of the pro's these days use 15 pounds. I like the extra power that extra pound gives me.
As for RVVTF.....I got out a year and a half ago when the covid craze started to die down and I could tell that the FDA was only giving BIG pharma the approval for covid treatments and vaccines. Smaller companies like RVVTF were being shut out from anything. IE.....it's all a scam.
The stock will probably hang around these levels for a while.
