It all depends on what school of tea you learn to whisk the tea, the type of chasen, and the chawan etc. A smooth chawan will be kinder to you chasen than a rougher one. I agree that you should soak your chasen in water really well to soften up the times.
However, if you use the chasen regularly, it's going to wear out eventually, but as long as you look after it properly, it should keep well. I have quite a few chasen, a couple of which have a few tines broken, but thats all part of the charm, plus you just take off the broken bits.
In my tea school (Ueda Soko Ryu of Hiroshima), if you're making thin tea, you whisk back and forth at 1 o'clock to 7 o'clock about 30 times, whereas making thick tea, you use a semi-circular motion 50 times for every amount of tea you're making. Other schools like Urasenke will whisk much longer in a W shape, while Mushanokōjisenke will whisk back and forth in an M shape.
Hope that helps. Happy whisking!
