Cello Strings

We all know that to get really good strings on a cello, one must spend a bunch of money, too much to experiment with new strings on a regular basis. When I moved to the US, I switched from Dominant to Spirocore, and soon I got Larsen for the A and D. For a long time, this was my favorite combination. For the C, I preferred the silver. I did try the tungsten, it was too strong and would not speak properly. For the G, I used regular Spirocore (silver being too unresponsive for my cello at that time).
So, just about a month ago, one of my ex-cello teachers, who plays with the Jerusalem Symphony - Cornel Faur - was in town; we were talking cello stuff and strings, and he said: "Try the Pirastro Permanent, they are the best in the world". Now, Cornel gets excited about everything he likes and he always believes things are "the best." I did more reading, the Permanent seemed to be recommended by many people, especially for their projections. Well, I am not sure they are the best match for my cello. The A seems to be much sweeter and stronger than the Larsen, the other 3 are sweet, but there is no kick. So, I am going to play them for a few weeks, maybe, and then go back to Spirocore, maybe with Permanent for the A.
