Maximizing use of CGT allowance - is this wise?

From what I can gather from other threads, there is a personal annual CGT allowance of Eur 1270, i.e. the first Eur 1270 of Capital Gains in a tax year are not taxed.

Does it make any sense to maximize your use of this allowance by cashing in sufficient investments (and immediately re-investing them) to avail of the allowance every year ?

Would the expected annual gain (Eur 1270 x 20% = Eur 254) be considered too little to be worth the time, hassle, and in some cases, fees, of doing this?

This is called a B&B (bed & breakfast deal) and you should be able to find existing threads on it. It used to be of more use when CGT was 40% and the annual allowance was transferrable between spouses. For a saving of €254 less broker charges and stamp duty on the buy back it might not be worth the hassle...
