Well, I held off selling for what sounds like much the same reason as you, I didn't want to pay full whack of tax by selling, in my case it's largely due to not having held for 12 months so I'm not eligible for the 50% CGT discount.
It appears that incentive not to sell has helped me hold on through a rally I thought had likely extended too far, I'm still hesitant to sell based on still not hitting the 12 month mark, I would definitely be selling now if it weren't for that.
Pretty happy with the colour green in my portfolio though, just have to do my best to ensure I don't get too greedy and remember to sell when I hit my valuation targets, for me that was $9-10, we are now through that and I don't believe the results I just read were enough to justify raising that valuation more than 50c at the most.
I would now call $9.50-10.50 full value, anything over being overvalued.
So now my call is full value but not overvalued and I generally move my sentiment to SELL when I think it's full value as I don't like to hold when it heads into overvaluation, this often leads to me selling too early, I also make the same mistake in buying too soon in the reverse scenario.

Ps: my sentiment is soooooo close to changing to SELL but not quite there, would love to hear any updated analysis from others, I'm not seeing this as a growth stock at this point as I previously had a few years ago, certainly dividend payout ratio supports that view IMO as otherwise more funds would/ should be getting reinvested into the business.
