Great points, Jon. I wasn’t going to buy the kit until I saw the tracks. Magic Factory pulls off RFM quality engineering, MF will become a personal favorite! 
If the metal pins fit properly it probably won’t be too bad. Annoying to glue half pads together but a least there shouldn’t be any punch marks on the tracks.
Worst case, mine will get tossed into a club raffle if the tracks are badly engineered. If the manufacturer was Dragon, I wouldn’t touch this kit with a ten foot pole.
