my main gripe with B2BS provincial would be its reliability, at times there were ball slippage problems that i feel like it shouldnt have happened when you loop. probably has something to do with the very stiff topsheet.
i dont find the short game to be as good as other tacky rubbers with B2BS prov, unlike other rubbers you really need to use a little more force to dig into the topsheet a little bit for decent spin on your pushes (again, probably due to the stiff topsheet). this comes with its own set of problems, meaning that you would have a difficult time controlling the short game.
last but not least is that the speed-spin ratio is borked if you're playing it unboosted straight from the package. speedy shots go out of the table bc theres not enough spin to pull it onto the table, spinny shots are not dangerous enough due to slow speed.
I would agree with you on this rubber if I kept playing it on a carbon blade - 729 Blue ALC.
But recently I switched to a 7 plywood stiff blade and I fell in love with this rubber on FH.
I have the 39 Prov BS version(mine is in red if that matters).
The thing I really like in this Battle is its linearity. I can control any ball if I'm in position.
Also I like the grip it has. I don't find any slippage issues if I play in normal conditions. I feel that I can lift the ball using only the topsheet unlike the D09c, for example. But if it is just a little bit humid the topsheet becomes like a brick and there is just no spin. Even H3 is better in high humidity.
Spin is good when it isn't humid. On H3 level. But if I sweat a little the spin disappears. I think because of the hard topsheet.
The sponge is solid and fast. It doesn't have the catapult the STN has and doesn't have the kick H3 has. It's just fast and linear and like it a lot. It's really easy to powerloop.
On Blue ALC I has like no dwell time and has little spin and no control so I didn't like it. Played both boosted and unboosted, don't find much difference.
Also I had some experience with B2 Nat BS 38 and B2 Gold 40. The National one is more elastic and has more easy spin. Lack some venom on the FH, though. On BH it was a dream but I switched bc is was sensitive to humidity. Gold one is good on FH, has even better grip than BS Prov but lacks some venom and has some catapult I don't like.
I think Battle series are really prone to the blade and to the conditions in the hall.
