MR 80's re-issue Twin Fin with FCS Plugs - pull plugs and glass on fins?

Hello Swaylocks, I have not been on here in some time.  I purchased a used MR 80’s retro twin fin on c-list that has FCS plugs and one has had a repair done (ugly but looks strong).  I have had twin fins rip out twice in the past with FCS (fin went to the bottom, expensive repari, etc…).  Question is; would it be a good idea to have the plugs drilled out and then foam filled and have a set of MR style glass ons put on? or would taking out the plugs weaken the board? 

thank you,

Harry

Never had a problem with FCS twins other than the plastic ones breaking. If it ain’t broke, don’t fix it. It’s gonna cost you the same if you do it now or wait until you have a problem which may never materialize.
