Considering they are not to low, any thoughts on whether it is better to blend in new hair with old plugs on the hairline or punch them out and start all over.

Anyone who has had either of these two methods, I would love to hear how things turned out.

If you look at Jotronic's website, he chose the first option with great (ie undetectable) results. Not sure about punching them out. Would that leave a (small) scar? Would you be able to fill that scar with FUs? If the density of the new HT is good enough to hide the results of the old one, I would leave them alone.
