I posted this elsewhere but just realised it was on a very old thread that may not be seen so trying again.

Iíve recently bought the Eastman OM and, while no expert, must say absolutely loving it.

A couple of beginners questions about changing strings to j72s please. I donít have very strong fingers and one of the things I like about the Eastman is how playable it is. It feels like my archtop guitar which almost plays itself! With higher tension of the J72s am I likely to find it noticeably harder to fret? Leading on from that, once youíve changed to the heavier strings, which seems to involve widening the nut and bridge slots, is it fine to revert to strings of the lighter, factory gauge or will they flop around in the widened slots?

I did say these were beginners questions!
