Closing doors - roller/ball latches or something else?

Guys, I have ordered two solidcore MDF doors without predrilling. To save some coin I am making my own seals right around the door with neopreane strips glued to a small cleats as discribed in one of Knightflys stickies. I am not sure how to get the door to seal up nice and tight against these seals seeing I don't want to drill holes though the door for a normal household door handle. Are roller/ball latches the best thing?. I was thinking I could put two (top and bottom) one each door and then just screw pull handle on each side. This way I should be able to get a nice seal by pulling/pushing the door into place. Am I on the right track? JG

Lucky for you, you can follow AlexT's footsteps! 8-)

Keith, perfect again as per usual - just what I had in mind and will save me $200 on two drop seals. Thanks JohnG
