Oren Grad
Well-known
Oren, the ST801 is a tad smaller than the SV. It's borderline: the ST801 is 5mm taller, but 8mm less in width than the SV.
And the ST605 and ST705 are actually a bit smaller and lighter than the ST801. Maybe not enough to be worth spending the money if you're happy with the ST801, though.
Hope you have some fun with that Industar!
