Softtopper question?

[eighteenninetytwo]

I have a softtopper for my 75 which is still packed in the box. It was the last white one and i bought it as they said they weren't making any more of them.
rigth now i'me juggling fixing up the hard top and refinishing it but it occurs that i wouldn't have to do all that if i just put the softtopper on and left it on. it highly unlikely I'd be driving this in the rain anyway and frankly here in the San francisco area the rain is telegraphed days in advance so that with anything more than a sprinkle expected it could be under a waterproof cover. Weighing the convenience of this against the originality of having the hard top . Does anyone take their hard top off and then fit a softtopper for the summer or one the softy is on do they tend to stay????
