I would hate to change everything she trusts right in the meat of the sectional season.
It probably won't last. FWIW, I'm getting 2.5 hours from the TB 1.30mm and 2 hours from the 4G.
4G is stiffer, and has less explosive power IMO. I much prefer TB in the 99S.
After my 4G popped today, I went back to a freshie with TB 1.30mm, I could tell a big difference.
