It’s very important, well for me it was anyway to get different opinions I’d say go with your gut feeling the one that made you feel comftable and just feels right. With surgeons they have to be honest with you hence although ‘abnormal’ did sound not nice to here, a surgeon is thinking of the nest results for you.
Doing your own research is very important too although you see surgeons And.the consult you there are pros and cons with every kind of placement whether it be overs or unders. You could ask the same question to the other surgeon who did not mention unders and see what he says
Goodluck x
