I went through this debate over the last year or so as I was looking to upgrade my sight. I spoke to quite a few folks on here and did some research and decided on a 3 pin slider for my use. I purchased from S&S (mainly because Steve was knowledgeable, patient, accessible and quick to respond to my questions) and got a custom MBG Ascent (4" Dovetail, 3 Pin Surge Head, top pins .19, bottom .10 with the rear facing sight tape). According to Steve it should be here the end of this week sometime. Look forward to trying it out...
