Ok, so I'm looking at the picture I have with the sizers. When I asked Dr Reath what size he'd recommend for me, he said 400. When I tried in the sizers I liked the 450s and 500s. If I go that big, mentor goes up by 50cc increments so I won't get to fix the slight difference in size which he said he will be about a 5%difference after surgery. So now I'm questioning if I should really go 500 or fix the size issue. Have any of you went bigger than suggested and regretted it? Have any of you gone smaller and wished you went with your gut and gone bigger?
